Description Colin Macdonald 2010-02-11 18:09:55 UTC
After updating to xorg-x11-drv-evdev-2.3.2-3.fc12.i686 from 2.3.2-2, my VGA output is limited to at most 800x600.  Output from xrandr shows external screen can be at most 800x600.  Internal LVDS still driven at 1280x800.

I'm using the intel driver on a Thinkpad X200.

How reproducible:

Downgrading to 2.3.0-1.fc12.i686 ("yum downgrade xorg-x11-drv-evdev") makes it work again.  No other packages changed.  

I don't know how to get back to 2.3.2.2 but it was certainly working on that version.

Comment 1 Matěj Cepl 2010-02-12 17:25:37 UTC
Thanks for the bug report.  We have reviewed the information you have provided above, and there is some additional information we require that will be helpful in our diagnosis of this issue.

Please attach your X server config file (/etc/X11/xorg.conf, if available), output of the dmesg command, system log (/var/log/messages), and X server log file (/var/log/Xorg.*.log) from broken configuration to the bug report as individual uncompressed file attachments using the bugzilla file attachment link above.

We will review this issue again once you've had a chance to attach this information.

Thanks in advance.

Comment 2 Peter Hutterer 2010-02-14 23:54:22 UTC
That seems a bit odd. The change from -2 to -3 was a simple patch to fix a condition in the driver from a (x == 0) to (x <= 0), and that was a pure driver-internal feature.

That aside, evdev is an input driver, so I don't know how that could affect the output in any way. Please provide the log files Matej asked for, because my gut tells me that there's something else going wrong.

Comment 3 Colin Macdonald 2010-02-15 01:08:56 UTC
I'm not confident any more either: the other day, at the beginning of a presentation, xrandr only did 800x600 (even with the older evdev which I'd been using for several days).

So likely it is something else.  Will try to narrow down what and provide the logs requested.  (Sorry, but bugzilla doesn't seem to let me leave it needinfo)

dmesg

lots of suspend/resume cycles in there.  But the last thing I did was connect a external panel and it was limited to 800x600.

Comment 7 Colin Macdonald 2010-03-08 16:37:03 UTC
Here's the output of xrandr when everything is working.  Next time it breaks, I'll send the output again (basically, VGA1 has no EDID data and only lists 640x480, 800x600).

Comment 8 Colin Macdonald 2010-03-08 16:41:01 UTC
I frigged around with the cable: pulling it in and out repeatedly, while suspending and resuming.

Now I've lost > 1024x768, but still have EDID (first time I've seen this):

Comment 9 Colin Macdonald 2010-03-18 16:17:51 UTC
Still seeing this after update to 2.6.32 kernel (2.6.32.9-70.fc12) and latest xorg-server (1.7.5.901-4.fc12).  Actually the  1024x768 limit mentioned above, but a limit nonetheless.

Comment 10 Colin Macdonald 2010-04-19 15:21:28 UTC
Still true in Fedora 13 Beta.

I can reproduce reliably by rapidly and repeatedly disconnecting/reconnecting my VGA cable.  Eventually the output becomes limited to 1024x768.

Comment 11 Bug Zapper 2011-06-02 16:36:21 UTC
This message is a reminder that Fedora 13 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 13.  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 '13'.

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 13'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 13 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: 
http://fedoraproject.org/wiki/BugZappers/HouseKeeping

Comment 12 Bug Zapper 2011-06-27 14:55:58 UTC
Fedora 13 changed to end-of-life (EOL) status on 2011-06-25. Fedora 13 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.
