Journal file after the upgrade

This is a journal after the upgrade.  I switched between plasma and mate so you may see a little of both in the log.

install log file

Thanks for the report, Brian.
It seems that you have at least Mate & Plasma. Any others in the upgraded system? What I am fishing for is whether this problems is specific to Mate, and other desktops upgraded OK.
Also, is the Mate desktop too bad to use? If not, a screenshot would be nice. Otherwise, a photo? Either to attach, to illustrate 'garbled'.

I did a fresh install of mate and the screen remained garbled.  Yes way too bad to utilize.  I had to force it to command line to get logged out.

Plasma worked.

I installed Xfce and that worked fine.

This seems unique to Mate.

Thanks for the further experimentation - which changes the aspect.

It seemed initially that the problem came from *upgrading* M7->8. Now it looks inherent in M8beta1. Do you know whether it was OK for M8alpha1?
Mate certainly works generally on M8, you are so far the only reporter of this issue. Which suggests a hardware/driver problem.

Can you please post just the "VGA" section of the output from:
 $ lspci -v
to elaborate on the driver in use; and attach /var/log/Xorg.0.log

I cannot pull the Xorg.0.log as it is gone.  Reformatted the drive to test btrfs

Missed answering your question about alpha1.  No this laptop was not tested in alpha1 so I don't have any history to provide.

Seems related to AMD APU related, not sure if anyone else is running an APU and can confirm this issue.

Thank you for the lspci output. As for the Xorg log, I suspect that whoever eventually looks at this bug will want to see it. Do you intend re-trying the Plasma + Mate installation on the re-formatted drive? i.e. Can we expect a log with the fault?

Sure but it will have to wait until next weekend sometime.

FYI - it will do it with just Mate installed as well.  So, it has to be related to the driver used by mate for R4 APU.

Started happening with latest updates on Xfce.  Was able to move to iceWM to get back to decent graphics.

Attaching the xorg log from the Xfce session.

xorg info xorg.log info

This is xorg from latest error from Xfce.  Having same issue now after updates from morning (U.S.A.) of Aug 2.

Thank you for the extra information, which widens the scope.
Re comment 12, can you post a list of what updates (not clearly irrelevant ones) were done to your system on that day? This might give a clue as to why Xfce started going wrong. You can see what updates were done on any particular day with:
 $ rpm -qa --last | less

Really unsure where to assign this, start with drivers, CC'ing tv for x11-server, Jani for desktops (please undo the CC if not relevant).

Installed filesI had grep'd some of the install files maybe this will help

ooops saved before I had a chance to comment properly.  Look at install on Aug 1.  That might be useful.
