F9PR x86_64 Live KDE: resolution not usable
Last modified: 2009-07-14 14:26:44 EDT
Description of problem:
I just booted F9PR (x86_64 Live KDE) on my Dell Inspiron 1720 and it was
anything but usable. The resolution is so small, even rhgb gets messed up (puts
the progress bar over the artwork). The pixels are that big, I can't read things
written in normal font size (KDE menu, display settings dialogs), because one
letter consists only of a few pixels.
Well, I really can't read something, so its hard to find anything out.
Steps to Reproduce:
1. Boot LiveCD
At the very least 800x600, better 1024x768. 1920x1200 supported by hardware (and
working fine with nVidia's proprietary driver and F8). I remember to have F8
working without the proprietary driver as well - can't remember the resolution
back then, tho...but it was usable.
I then tried to logout, which resulted in a black screen with some pink/white
blinking bars (not always the same size/position/etc).
Oh, the component is a wild guess. I don't know which driver was used.

grub working fine
...ok, that's been the last image. sorry for the bad quality, they've been made
with my mobile phone.
uh, I forgot to mention, that I didn't boot from CD but from liveUSB...sorry.
no persistence, tho.
Even though you have no true persistence is available you should be able to get
some files stored somewhere (scp, ftp, another USB drive, something). So, would
you be able to attach your X server config file (/etc/X11/xorg.conf) and X
server log file (/var/log/Xorg.*.log, or maybe something in /tmp, I am not sure)
to the bug report as individual uncompressed file attachments using the bugzilla
file attachment link below.
We will review this issue again once you've had a chance to attach this information.
Thanks in advance.

Xorg.0.log shows that no config file was loaded, and indeed. there's been no
xorg.conf. Even tried updatedb && locate xorg.conf and it only showed the man

maybe some other infos will help, so I'll attach what came to my mind.
btw. the vt is working/usable, so I can do cmd line stuff to help solve this.

actually this is the lsmod output. the "messages" file seems to be empty.
Your laptop is made of lies:
(II) NV(0): LVDS native size 738x414
So we try to pick a mode that fits in that size.
What's the output of 'hexdump -C /proc/acpi/video/*/*/EDID' ?
How does it come then, that it worked fine with F8?
I've executed the above within my installed F8 and not within the live system, I
hope that's ok. Just tell me otherwise. Output is:
$ hexdump -C /proc/acpi/video/*/*/EDID

Changing version to '9' as part of upcoming Fedora 9 GA.
More information and reason for this action is here:
This message is a reminder that Fedora 9 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 9. 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 WONTFIX if it remains open with a Fedora
'version' of '9'.
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 prior to Fedora 9's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 9 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 please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.
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.
The process we are following is described here:
Fedora 9 changed to end-of-life (EOL) status on 2009-07-10. Fedora 9 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version.
Thank you for reporting this bug and we are sorry it could not be fixed.
