Red Hat Bugzilla – Bug 187821
Blank screen on Acer Aspire 1692
Last modified: 2007-11-30 17:11:29 EST
Description of problem:
I had to install FC5 in text because GUI did not start, screen stayed blank.
After installation when I run system-config-display screen goes blank and
nothing happens. Hitting Ctrl-Alt-BS gets me back to command prompt.
Version-Release number of selected component (if applicable):
FC5 + latest updates as of 2006-04-03.
Steps to Reproduce:
1. Install FC5 to an Acer Aspire 1692 laptop
2. Run system-config-display
3. See how screen remains blank
Screen remains blank.
X configuration screen is shown.
I'll attach dmesg and X.setup.log outputs. Sticker on the laptop says:"ATI
Mobility Radeon X700 PCI Express With 128MB VRAM."

So, any news on this? Fedora Core 5 on my laptop is practically useless until
this issue has been fixed. Please tell if you need more information and I'll
happily provide it. Thanks.
I got X running with ATI proprietary driver from rpm.livna.org.
system-config-display did not work without an existing xorg.conf. With the
attached xorg.conf both X and system-config-display work all ok. Please consider
fixing system-config-display and/or default X drivers so that I could get even a
low-resolution on my laptop.
I'll attach xorg.conf, dmesg, X.log.

my xorg.conf that works with ATI proprietary driver
Good news! I finally managed to get X working on my laptop without ATI
proprietary driver. The key was to add the following line to xorg.conf in video
card section, without it the screen stays completely blank and even
system-config-display won't start. With it both GNOME/X and
system-config-display work ok (1200x800@24).
Option "MonitorLayout" "LVDS"
I'll attach my full xorg.conf and both dmesg output and Xorg.log after starting
and quitting GNOME.

So what's the status with this? All information needed should be available to
roll out a package containing needed fixes. Thanks.
The X log attached for the failure case is just the stderr output, not the log
file. What does the log look like if you start X without the MonitorLayout option?

Sorry for the previous incorrect log, this log now really contains X log after
executing startx and ending the sessions with Ctrl+Alt+BS because screen
remained blank. My system is FC5 plus all the updates to date.
The installer still halts, screen remain blanks after a few moment with FC6t3.
This is still happening with Fedora Core 6 (Zod) Final.
I will attach logs generated when attempted to install FC6 in graphical mode.

I don't want to push you but it's been three months without any comments and
over half a year since this bug was created and still you can't use Fedora Core
on an Acer Aspire 1692 without resorting to manually tinker with a config file
that should be automagically adjusted by system-config-display.
If you need some additional information please say so and I'll be delighted to
provide if to you.
This one's pretty weird. We don't get DDC from the panel, and we don't seem to
find any timing info for it in the BIOS, and there's certainly no VGA attached.
So we're trying to do 800x600 as the fallback, but apparently even that fails.
So we may be stuck, unless there's another way out. Do you have any
subdirectories underneath /proc/acpi/video ?
Thanks for looking into this. Indeed, there is "VGA" subdirectory. I've attached
its contents as a tar.gz archive.

Okay, so looking for EDID in ACPI was a dead end.
The real problem here is that we're not finding the connector table.
