I installed Leap 15.6 on a new Dell XPS13 (Intel) and there is some sort of a graphics card software issue. Rendering of Xwindows is slow and the cursor seems to vanish at times or move too slowly at other times. It is not a hardware issue because I dual boot with Windows 11, where there is no such problem. Also, the problem persists whether I use the trackpad or an external mouse.
Output of inxi -GSaz:
(I had to backport to 6.15 in order to get the Wi-Fi 7 Intel BE201 wireless card to work with the kernel, but the problem existed also with 6.4.)
Thank you in advance for any pointers.
@pgpbear Hi and welcome to the Forum 
I suspect based on your inxi output as only using llvmpipe your missing all or some of these packages: intel-gpu-tools intel-media-driver libze_intel_gpu1 intel-opencl libvulkan_intel
If that doesn’t help, then you need to raise a bug report, you should also do that for the WiFi issue…
Thank you - I installed all the suggested packages except for libze_intel_gpu1, for which I could not find a clean Leap 15.6 version, to no avail - the problem persists.
@pgpbear can you show the output from inxi -GSazI suspect there will need to be some backporting, but Leap is probably not a good release for that harware as it’s too new…
Thank you - here it the output of inxi-GSaz:
Also, lspci -k | grep VGA yields
Please post output in pre-formatted text (</>), so we can quote from it.
@pgpbear I don’t think the Leap software is up to speed with your hardware… I suggest you create an XFCE Tumbleweed live USB and test that.
Sure - here the pre-formatted text version of the inxi -GSaz output:

I tested the XFCE TW live USB and booting is stuck after
“Starting Show Plymouth Boot Screen”
I was able to boot in fail-safe mode and get limited Xwindows functionality with startx: single xterm and a Firefox window - both graphics and wireless seem to work
in this limited setting.
Did you try again, striking the ESC key quickly after leaving bootloader menu, to look for clues among the boot messages? Plymouth’s purpose is to hide boot messages with a graphical curtain, just like Windows, and and to avoid seeing modeswitch glitches.
This may be relevant - here is what I get from

Sorry I cannot make good sense of this - thanks in advance for any pointers.
Thanks - tried several times, but nothing more shows - still stuck at Plymouth…
It appears like you may need to install newer Mesa to go along with newer kernel. My method would be by first saving this repo file to disk, copying it to /etc/zypp/repos.d/, refreshing, then replacing all installed 23.3.4 Mesa rpms from that repo. Current there shows 25.1.1. You could do this in YaST, but last time I did it by the book using only YaST or zypper ar was far too long ago to provide specific instruction how.
@jsmith64 Leap 15.6 is too old. The openSUSE Tumbleweed Mesa version already has Intel RayTracing support activated…
The Xe driver is also missing some features in Wayland… one has to set environment variables for some applications to work…

I don’t know about Leap and I didn’t see force being mentioned, so I posted that so those of you who were trying to help would know you have to force the driver with a kernel parameter. If Mesa on Leap is older than 24.2 then this wouldn’t even work.
Thank you for this suggestion - I tried this but have now introduced an incompatibility between the kernel and the installed version of the Mesa library, as in:
glxinfo -B
name of display: :0:0
Error: couldn't find RGB GLX visual of fbconfig
Perhaps time to declare defeat…
Would you consider installing Tumbleweed or Slowroll? I like the latter as it provides a stable rolling release experience, with a major monthly upgrade cycle, along with smaller more frequent security and bug-fix updates as they are released.
I will definitely give one of these two a try… I was unable to get the latest Intel Wi Fi 7 card to work with 6.4 and only managed to make it work via backport to 6.15 (which is what Tumbleweed is using). I understand that Slowroll is using 6.12, so this is one area of worry…
