ASPEED AST2400 graphics failure (skewed - wrong stride) in Wayland sessions including the login screen

[Filip Roland]

I have an ASUS P10S-I server motherboard with integrated ASPEED AST2400 VGA chipset.
With earlier Ubuntu version (maybe on Ubuntu 16.04.3 ?) it worked well.
Once when I updated (but before the actual version) it went wrong.

To be truth it not really the xresver...-ast's problem because this earlier not installed automatically and the poroblem was the same. When i found it on synaptic as uninstalled i hoped that this will solve the problem and i had installed it but it not worked at all...

The issue:
When I boot normally the login window load slowly and keybord and mouse very slow too but work.
I can login. But after i login the screen not show the desktop it show diagonal stripes. (see the attachment)
This stripes made from original screen but unrecognisable the things. But the items work if you can click the right places. (for example i can click on the main switch button if i have luck and Crl+Alt+Del log out me.)
After i log out the login screen corrupted on the same diagonal stripe way. But also work I can re login.

How it work:
If I start the recovery mode and on the recovery window choose continue start normally (and nothing else needed) it works without problem. Evrithing is fine.

I tried to install ASPEED driver but on the Softwares and Updates menu Another driver don't found it.

Can you please try editing /etc/gdm3/custom.conf and uncommenting this line:

 #WaylandEnable=false

Then reboot, but make sure you're not rebooting into recovery mode again.. Does that fix it?

[Filip Roland (froli)]

Dear Daniel!

I did what you wrote and that worked!

The problem is solved permanently!

Thank you very much!
