Description of problem:
When setting xorg for 10-bit Depth / DefaultDepth in /etc/X11/xorg.conf we get, after restart of xorg, a desktop that is unresponsive to mouse clicks.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
Working desktop, responsive to mouseclicks, at 10-bit Depth.
There supposedly is an 'upstream' fix but this ha not reached us in many many months.
10-bit is per channel of RGB.
So the xorg.conf will look something like:
- xorg does 30 bit OK
- my monitor's specs say 3*10 bit is no problem
- the fix is 'upstream'
- so what are we waiting for?
Tested with fedora 30, git amdgpu and git mesa and again same behaviour.
So we have incomplete hardware support in gnome:
Not the full Depth/Defaultdepth in /etc/X11/xorg.conf *and* no fractional scaling for hiDPi screens out of the box...
This message is a reminder that Fedora 31 is nearing its end of life.
Fedora will stop maintaining and issuing updates for Fedora 31 on 2020-11-24.
It is Fedora's policy to close all bug reports from releases that are no longer
maintained. At that time this bug will be closed as EOL if it remains open with a
Fedora 'version' of '31'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version.
Thank you for reporting this issue and we are sorry that we were not
able to fix it before Fedora 31 is end of life. If you would still like
to see this bug fixed and are able to reproduce it against a later version
of Fedora, you are encouraged change the 'version' to a later Fedora
version prior this bug is closed as described in the policy above.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
I tried 30 bit by removing allow_rgb10_configs=false from /etc/environment
and using Depth 30 and DefaultDepth 30 in /etc/X11/xorg.conf.
Then we went to single user mode, waited for gdm to go away and back to runlevel 5.
There stuff appears to work:
$ xwininfo -root | grep Depth
Would that be enough proof of 30 bit working?
