Xorg vs x11

Like many of ArchLinux users after upgrade to Gnome 3.

Pyspark create table

So I want to use xorg x11 like before the update instead of wayland until these bugs have been repaired. I'm using gdm as session manager. So, I need help to correctly set gdm to only use xorg x11 like before to upgate to Gnome 3.

Thanks you to all who spend their time to help me and to help the other users who come here with the same problem :. I have read the wiki before post in the forum, I shoud say it in my original post, will edit.

The problem is that I don't know how to configure gdm, or where is their options menu or what are their options commands.

X Window System

It's for that for what I'm asking for help :. When you login, after selecting your user just click the gear icon below the password field and select "Gnome on Xorg".

Then finish logging in. That selection will be saved and future logins will use is by default. Don't mess with the gdm user file there, do it on your user file. Thanks you very much leebickmtu, I did what you said there and now looks like all problems I have with gnome 3. I didn't need to do anything else. Now, I'll mark the post as solved, but, just to finish, I would like to say for the people who comes to this post with the same error that I already have uncomented the option 1 as I said on my first postbut I reverse the changes done in the options 2 and 3.

X provides the basic framework for a GUI environment: drawing and moving windows on the display device and interacting with a mouse and keyboard.

As such, the visual styling of X-based environments varies greatly; different programs may present radically different interfaces. The X. Org Foundation leads the X project, with the current reference implementation, X. Org Server, available as free and open source software under the MIT License and similar permissive licenses. X is an architecture-independent system for remote graphical user interfaces and input device capabilities. Each person using a networked terminal has the ability to interact with the display with any type of user input device.

In its standard distribution it is a complete, albeit simple, display and interface solution which delivers a standard toolkit and protocol stack for building graphical user interfaces on most Unix-like operating systems and OpenVMSand has been ported to many other contemporary general purpose operating systems.

X provides the basic frameworkor primitives, for building such GUI environments: drawing and moving windows on the display and interacting with a mouse, keyboard or touchscreen. X does not mandate the user interface ; individual client programs handle this. Programs may use X's graphical abilities with no user interface. Unlike most earlier display protocols, X was specifically designed to be used over network connections rather than on an integral or attached display device.

X features network transparencywhich means an X program running on a computer somewhere on a network such as the Internet can display its user interface on an X server running on some other computer on the network.

The fact that the term "server" is applied to the software in front of the user is often surprising to users accustomed to their programs being clients to services on remote computers.

Here, rather than a remote database being the resource for a local app, the user's graphic display and input devices become resources made available by the local X server to both local and remotely hosted X client programs who need to share the user's graphics and input devices to communicate with the user.

X's network protocol is based on X command primitives. This approach allows both 2D and through extensions like GLX 3D operations by an X client application which might be running on a different computer to still be fully accelerated on the X server's display. For example, in classic OpenGL before version 3.

X provides no native support for audio; several projects exist to fill this niche, some also providing transparent network support. X uses a client—server model: an X server communicates with various client programs. The server accepts requests for graphical output windows and sends back user input from keyboard, mouse, or touchscreen.

The server may function as:. The communication protocol between server and client operates network-transparently: the client and server may run on the same machine or on different ones, possibly with different architectures and operating systems.

A client and server can even communicate securely over the Internet by tunneling the connection over an encrypted network session. An X client itself may emulate an X server by providing display services to other clients. This is known as "X nesting". Open-source clients such as Xnest and Xephyr support such X nesting.

The remote X client application will then make a connection to the user's local X server, providing display and input to the user. Alternatively, the local machine may run a small program that connects to the remote machine and starts the client application.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

Quartz is the set of technologies that are in the OSX Core Graphics that deal with 2d from wikipedia. In the macports variants. XQuartz but use Apple's graphics directly and not via X11 so not calling any X. If you want to keep independant your future upgrades of XQuartz and MacPortsthen you will have to keep both installations.

If you remove a needed library within the install path of MacPorts it will have to rebuild it. On the other hand, it will never upgrade anything when you modified the XQuartz version because it is outside of its managed source and install tree.

If I understood correctly I'm free to remove X.

Org which was installed by MacPorts, as long as I leaf XQuartz installed because it already provides the needed libraries?! I really don't want to waste storage.

Sorry also true re OSX Also if you have an X. This practical way of managment stand without problem since Snow Leopard up to Sierra.I originally planned to use the i3 window manager, but then I learned that Wayland is the more secure, more lightweight successor to Xorg, and that Sway is basically a drop-in replacement for i3 using Wayland.

Then I learned that Nvidia are very bullheaded regarding how their driver handles Wayland, so Sway won't support Nvidia proprietary drivers in the future.

Since your laptop has only p that should be of no concern for you. Is wayland more secure than Xorg? But only in the way that my display server, the full source code of which is below, is even far more secure than either of them:. Wayland probably does a couple of the things you want it to, so you can judge how useful it is compared to Xorg despite being somewhat more secure.

Xorg will do pretty much everything you'd want, with the potential of being slightly less secure in some particular conditions which may not even be relevant on your machine. Then also keep in mind, if you want to run any programs in Wayland, you'll likely be running Xorg anyways, just as a child process of your Wayland compositor.

Hi there, welcome to the boards. Not exactly a direct answer to your question regarding Wayland and it boils down to what level of isolation you need, Xorg is fine just don't run it as root in the first place but I wouldn't do that with Wayland either There are other ways to create isolation.

Thanks guys. So basically Wayland is more secure, but Xorg doesn't need to be actively worried about. Or to put it another way, there are probably much larger security concerns to deal with first if one is worried Xorg vulnerabilities.

One has to walk a fine line between having a reasonably secure system and not spending all their time trying to patch every way to get into a system. Maybe I should clarify that: there's a design aspect in X11 that makes perfect process isolation impossible. Wayland compositors try to deal with that, but that doesn't inherently make them more secure. You will never have perfect process isolation on a desktop system, because you want to transfer data between processes aka copy and paste and there's IPC everywhere.

The actual security depends on the implemented channels and guards and their quality. Otoh it's perfectly reasonable that there can be bugs in unrelated parts of the wayland compositors which tend to be pretty damn complex, where sway is rather on the skinny side that can bleed over into the compositor - esp. An interesting read. I wonder if there are any Nvidia engineers that wish they could open source their driver. Wayland isn't complete, also most of gnulinux gui apps use xorg they launch on wayland by Xwayland compatibility xorg server for wayland.

Sway doesn't support my nvidia gt, and nvidia driver at all you need to use nouveau driver with sway. Many of their engineers are open to it, but I think that the engineering culture at Nvidia is unhealthy and that the engineers have very little influence.

I remember sometime ago there was a similar thread about choice between Wayland and Xorg, but that time from the programmer perspective.

The person was interested in whether Wayland security model fits his needs.

After some days of research the person was highly dissatisfied with restrictions applied by Wayland. Regarding your question about security. If you are the sole user of laptop, then using Wayland instead of Xorg would hardly make your laptop secure.

xorg vs x11

Until the Wayland developers get their heads out of their asses and add support for the features that Xorg users already use, Xorg is still needed. Fortunately, it appears they are working on a remote desktop API… Good. The best thing that Wayland development has done for the Linux community was get developers to tell Nvidia to fuck off.

Using Xorg and XWayland. Still a bunch of problems with both, but by the time Wayland finally decides to add the functionality people want they will probably have decided to make X That is what Wayland was meant to be in the first place, not a replacement for X. Wayland seems to have changed over the years to want to be an X replacement but only time will tell where that one will go.

Going to be funny if it does end up replacing X and years from now we are all talking about how buggy and bloated Wayland is and that we need to replace it….

Have been running Wayland on Fedora for a couple of weeks now. No Problems so far. But no real benefits either. Intel Integrated Graphics. You loose redshift and color pickers the big ones for me personally. At home, i run on nvidia, so wayland is a big nope. As someone who consistently is running 2 or more screens, often mixed resolution, dpi and refreshrate, wayland would provide major benefits, if nvidia would support it.

I truly believe that wayland will be the future.

The current problem is, that the benefits are only felt by very few people. You basically need to be running something that needs mixed dpi, mixed refreshrate, fractional scaling or something like that and not be on Nvidia. And even then you are currently making some sacrifices.

xorg vs x11

If in doubt, use X11 and watch wayland progress from the sidelines. Wayland will get there. Especially when all other components need to adapt to it. They wanted to focus on the whole Display and compositing stuff and leave the rest to someone else.

Everyone needs to figure out who to implement it and what else is needed to drop X I use the panning functionality via xrandr occassionally. What exactly do you think is missing other than no remote desktop integration. Imo its fair for wayland not to have that. I run wayland on my notebook now and so far everything worked.

I know gparted is a thing that needs a workaround on wayland, but thats not because of missing features but rather because of tighter security constraints per default.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

Ask Ubuntu is a question and answer site for Ubuntu users and developers. It only takes a minute to sign up. What is the difference between ssh -Y trusted X11 forwarding and ssh -X untrusted X11 forwarding? As far as I have understood it, it has something to do with security, but I did not grasp the difference and when to use which. Both options have something to do with X11 forwarding.

This means if you enable this, you can use a graphical client through your SSH session e. If you use ssh -X remotemachine the remote machine is treated as an untrusted client.

So your local client sends a command to the remote machine and receives the graphical output. If your command violates some security settings you'll receive an error instead. But if you use ssh -Y remotemachine the remote machine is treated as a trusted client. This last option can open security problems. Because other graphical X11 clients could sniff data from the remote machine make screenshots, do keylogging and other nasty stuff and it is even possible to alter those data.

If you want to know more about those things, I suggest reading the Xsecurity manpage or the X Security extension spec. Use neither when you don't need to run X11 programs remotely; use -X when you do; and hypothetically use -Y if an X11 program you care about works better with -Y than with -X. But currently Ubuntu Both ssh -Y and -X let you run an X11 program on a remote machine, with its windows appearing on the local X monitor. The issue is what the program is allowed to do to other programs' windows, and to the X server itself.

Trusted X11 forwarding is enabled by -Y. This is the historical behavior. A program with access to the display, is trusted with access to the entire display. It can screenshot, keylog, and inject input into all the windows of other programs. And it can use all X server extensions, including ones like accelerated graphics, which are security exposures. Which is good for running smoothly, but bad for security. You are trusting the remote programs to be as safe as your local programs.

Untrusted X11 forwarding tries to restrict remote programs to accessing only their own windows, and to using only those parts of X which are relatively secure. Which sounds good, but currently doesn't work well in practice. On Ubuntu If ForwardX11Trusted nothen -X enables untrusted forwarding.

Otherwise, -X is treated the same as -Ytrusting that remote programs with display access are friendly. Ubuntu Community Ask! Sign up to join this community. The best answers are voted up and rise to the top. Ask Question. Asked 9 years, 3 months ago. Active 10 months ago.
