I have just ran an Cyberpunk 2077 benchmark on Fedora 40 using an AMD 7900XT, 4K resolution (FSR2.1-Quality), all Ultra (or high) settings, and no RT. I got 70 fps! This is as good as (or better than) Win11. Can anyone try and confirm?

Mathlab default under Wayland is use the qt wayland backend. Yes this link is user running into one of the edge cases where matlab has a issue when using Qt Wayland backend. Yes forcing xcb so it used xwayland is required to work around some issues at this stage.

With easy access to high-performance computing (HPC) clusters, many users may feel confused about which cluster to choose and if HPC is actually useful for their research. I will outline some basic considerations users should go through to see if HPC is suitable and if yes, which type.
HPC clusters often work with a queue system and so GUI use is not standard. However, on most clusters a user can request what is called an interactive session via the queue which gives them direct access to one of the cluster’s nodes with restricted resources (cores, memory, time limit, etc.) as requested from the queue. The user can then bring up the GUI and run the calculation on that node. However, this has some limitations. Interactive sessions are often restricted to a few at the same time, putting a limit on how many calculations can be done. Users also need an X Windows session when accessing the cluster to be able to display the GUI (usually a problem for users’ Windows desktops).
Even at the university level not all HPC clusters will have interactive session as option. Yes no interactive session also means no VNC or anything else. HPC systems that don't provide interactive sessions also don't have any use for X11 or Wayland. Yes someone ssh in counts as one of those interactive sessions so no interactive sessions means no ssh in to use command line either.
Yes a HPC cluster with over 10000 new students assigned is likely to have a max interactive session count less than 10 so the odds of being able to use the interactive session at a normal time of day is almost zero yet you can que a job and collect results any time. Also the interactive sessions are normally given fairly low CPU access priority. Do note that they clearly mention there is a time-limit on how long your interactive session on the HPC can run before it terminated. A non interactive job is allowed to run longer.
When you get into the finer details the Universities provide X11 and VNC and others in the training stages to use HPC. Once you are trained that take that stuff away. This is why the top500 is no help to X11 development because they don't in fact use it. Once you get right up in the high end HPC they don't use X11 over network or remote desktop in any way heck using ssh into a processing node is not even possible.
mSparks in HPC there is line is HPC size where X11/vnc/xpra/ssh... all forms of interactive interfaces just cease to exist. When you cross that line you have queuing up jobs and collecting generated results as your only way to interact with the HPC cluster. Yes I do even mean cease to exist for system administration as well because you are using clustered configuration management solutions. Top500 are all on side of the line of no interactive.

X11 is a project developed and deployed by hundreds of different companies, including every single one of the top 500 HPC machines.
The last release of XCB was 15th April 2024, fixing up python bindings.
It's ahead of wayland in every single aspect, including things like VR, HDR and VRR that only started happening meaningfully in the last couple of years.
Is it you are confusing "dead" with one company (redhat) saying they will only sell wayland support packages after 2025?
X11 is not dead
Wayland is - to the point I already uninstalled it.
Wayland is nowhere near dead. We are still getting new features merged all the time. Just look through the damn headlines right on this sight.
Keep burying your head in the sand if you want. Doesn't matter to me. Just please stfu about it while you do. None of your complaining is accomplishing anything other than being a fucking annoyance to the users of the forum.

What development do you think is missing from X11 that wayland is achieving?Last edited by mSparks; 22 April 2024, 02:32 AM.

There is no option to use wayland.
There are no other options.
plus, the rest.

X11 Vulkan has proven itself time and again to give the most "flawless" experience, CP2077 is a Vulkan game, so this sounds about right.
Hi, as some of you have seen in the news, in general, the state of the X server in the Linux ecosystem is not in a good shape. This problem is worse if you have newer bits in the distro (new mesa, etc etc) so Clear Linux has been suffering various intermittent “X does not work with hardware Y” issues at times. I want to post to make clear where things are at in this regard for Clear Linux. It should be of no surprise that Wayland is the future of the desktop Linux ecosystem – and it is for us ...Last edited by mSparks; 22 April 2024, 03:14 AM.

On compute clusters Matlab has been falling out of favor due to how often you are forced to use a GUI to debug what in heck has gone/going wrong on the cluster. Octave, Julia and Sage all have good debugging information dumped into a failed run data from a non interactive session.
