Red Hat Bugzilla – Bug 221789
video display is distorted
Last modified: 2008-11-18 19:30:15 EST
Description of problem:
After booting the X display is garbled and unclear while switching to virutal
console screen is very clear. Garbled screen clears up after switching to a
virutal console and switching back to X (F7). The machine is a Dell Precision
470 and has an Nvidia NV44 [Quadro NVS 285] (rev a1) video card. I am only
running stock RHEL5 packages. It appears that RHEL5 is automatically installing
and using the "nv" driver.
I have been seeing this problem for the past 3 few weeks running while contining
to update to the latest nightlies for RHEL5. Today I reinstalled my machine
with RHEL5-Client-20070105.0/4.92/x86_64/os (latest snapshot) to make sure I had
a clean install.
Before the reinstall I would see this problem once every 3 or 4 boots... I power
the machine off each night and power on each morning.
Version-Release number of selected component (if applicable):
rpm -qa | grep ^x
Steps to Reproduce:
1. Boot the machine
Sometimes the screen and fonts are garbled (see screenshots)
Screen is clear 100% of time time.

Admitedly the work around to switch to a virtual console and switch back to X is
fairly easily, but the appearance of the screen is a horrible first impression
to give our customers about the quality of our product.

xorg.conf--as created automatically by installer
which is a trivially correct fix already present in rawhide. Does it work if
you install the nv driver from rawhide?
I read through the Novell bug and it is hard (for me) to see how it is the same
issue I reported.
Please provide a pointer to the exact package(s) that need to be installed from
https://bugzilla.novell.com/show_bug.cgi?id=220197#c25 - describes screen being
garbled and then fixed by VT switch.
- is the nv driver currently in rawhide.
installed xorg-x11-drv-nv-184.108.40.206-1.fc7.x86_64.rpm and am running it on my
primary desktop. Haven't seen any issues so far. I don't know an easy way to
trigger the original problem I was having to say for sure that this driver fixes
the problem. I did do a few reboots and everything looks fine so far. I'll
keep you posted if I see any other weirdness.
Just booted machine from cold state seeing the problem reported. I watched the
entire boot process and the distortion firs appears at the gdm login screen.
I'm still running the nv driver from comment#10
Move to 5.1. We're not likely to get this done for 5.0, as the nv driver is
sufficiently obfuscated. Should engage nvidia on this though, and would be a
I propose that at least a release note be considered for 5.0 for this issue.

Agreed, although it may be too late to get it translated...
"When starting the graphical installer or graphical login, some NVIDIA cards may
display corrupted graphics. The workaround is to switch virtual console and
back to graphics."
John, have you seen this issue with the nv driver in F7? I'm essentially going
to be backporting that driver anyway, would like to know if it's two birds with
one stone here.

What package versions would be helpful to know if I'm running?

Have you tried xorg-x11-drv-nv 2.1.0 in F7 yet? Has a fix for something that
sounds like a similar problem.
i just installed 2.1.1-1.fc8 from rawhide to my F7 box... will see how it goes.
If you want me to run a specific version, please send me a pointer to its location.

Yeah, probably a good idea.

No adverse affects. Seems to be running well. I don't recall having to switch
to a virtual console to clear the screen since running this version.
as per John's report, not adding this to the RHEL5.1 release notes. seems to
have already been resolved. if anybody thinks this assessment is premature and
the relnote is still needed, please advise. thanks!

Sadly... I just encountered the problem again. Had to switch to virtual console
3 times to clear the display from the login screen.
Trying to reproduce this is difficult if not impossible because I do not know
what cause it to happen.
thanks for the heads-up, John. adding this known issue again to RHEL5.1 release
Fixing component, xorg-x11 isn't included in RHEL5.
I don't have a good lead for this, so I'm retargetting for 5.2.
No known solution yet. Will miss 5.2 unless we figure it out.
I _think_ it's just a palette setup bug, but that should be the same between the
init and vt-switch paths.
same release note added to "known issues" section of RHEl5.2 release notes.
please advise when resolved. thanks!
John have you got this machine and F8 or rawhide? I've just pushed a rawhide
xorg-x11-drv-nv-2.1.6-5.fc9 and I'm going to scratch build some F8 test packages,
f8 scratch packages are http://koji.fedoraproject.org/scratch/airlied/task_356197/
I got the idea for the fix from the nouveau guys.
I might just put the patch into RHEL5.2 as it won't break anything.
pushing out to 5.3 due to not having time before 5.2 freeze.
Dave, I still have the hardware and am running F8. I've installed from the koji
link above and will let you know if I see any problems. It is intermittent so
hard to reproduce and could take a while to appear.
the RHEL5.2 release notes will be dropped to translation on April 15, 2008, at
which point no further additions or revisions will be entertained.

FWIW.... still seeing the problem with latest rawhide packages (2008-APR)
