Title:
xorg on Ubuntu 20.04 fails to show correctly background image and
icons
Status in xorg package in Ubuntu:
New
Bug description:
Hello I have PC with Xeon E processor and I am using integrated Intel
graphics to drive a VGA display. I am using Ubuntu 20.04 Everything works fine.
Then I add xorg.conf file, for other reasons, to /etc/X11 ( by default no
xorg.conf file is present ) and I get the first screen after the log in is
corrupted by yellow vertical lines and/or corrupted icons and eventually a
block box is present at half height of the screen. See here below the
incriminated xorg.conf :
Section "ServerLayout"
Identifier "layout"
Screen 0 "intel"
EndSection
Section "Device"
Identifier "intel"
Driver "intel"
BusID "PCI:0:2:0"
EndSection
Section "Screen"
Identifier "intel"
Device "intel"
EndSection
and photo of the corrupted screen is attached.
If I open terminal or what else looks good but the first screen is always a
bit corrupted. If I change the background image , the new background appears
without vertical lines. If I go back to the original background image that is
still corrupted with vertical lines. I am sure the corruption is because of the
xorg.conf file but how can I fix the situation ? I need the xorg.conf file
because I want xorg.conf to use only the internal integrated intel graphics and
not other graphics cards/drivers that will be present.
If I do exactly the same , adding the same xorg.conf file to on Ubuntu
18.04, same HW, same configuration, I don't see this problem. It
happens only with Ubuntu 20.04.
