Graphics Problem after updating Dom0

[Mystic Buyer]

Hi guys

I hope someone will be able to help me out on this. So I just installed Qubes 3.2 on my Dell xps 15 9560. Things worked perfectly until I updated dom0. After the dom0 software was updated (like I read on some posts to Fedora 24, not sure though). The graphics seems to have broken completely.

*Touchpad does not work correctly after the login screen. Responds in glitches.

*The screen has slowed down. Everything typed responds very late. And dom0 says "ClockVM failed to start. Exiting." Not sure what that is

*The windows seem to respond like curtains falling from bottom down.

If someone can tell me what is wrong and if some solutions that can be applied.

Thanks.

Honestly, I think there is no solution, must wait for the devs to fix
it, and/or install on a different system, on my 2nd system skylake the
dom0 update didn't cause the same problem as it did on kabylake .

Sure wish Linux had some kind of restore point or something as a
fallback ....:)

Yes I did observe that when I installed qubes on acer aspire, configuration not as good as xps 15.

Except the touchpad doesn't work. But everything else works perfectly fine even after the dom0 update no problems at all.

I updated my dom0 on xps 15 to unstable repo as mentioned in some other posts and it did solve the problems, everything after the update to unstable repo on xps 15 is working fine.

One thing to try (assuming that it's an Intel video card in your machine
and not an Nvidia one, but I don't know if it'll help) is to enter into
the Advanced Options menu when GRUB starts up (I don't know how it works
with UEFI) and under the 'module' line, add
i915.preliminary_hw_support=1 right after 'quiet' and then try to boot
with that option. Let me know if it does and I'll make it a default
setting in the 4.4 kernel in my next Pull Request.

As for VM graphics issues, there are some packages in current-testing
for all the various templates that may help with the slowness (mainly to
do with qubes-gui-agent); if you have the ability, see if installing
them helps with your issues. It did seem to help with mine.

Not sure what's happening with the touchpad driver; from what I can
tell, nothing has changed in regards to the kernel options between
4.4.55 and the previous one when it comes to touchpads. There *is* an
updated dom0 kernel in current-testing (4.4.62) that you could try to
install to see if that fixes things.

If you have the ability to compile your own kernel, you could try
compiling a 4.9 or 4.10 version using the instructions here (if you're
compiling on an fc23 template, you'll need to grab the
qubes-kernel-vm-support package from current-testing first since it
hasn't made its way to stable yet):
