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.
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.
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.
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)
Created attachment 397323 [details] var_log_messages
Created attachment 397324 [details] Xorg.0.log
Created attachment 397325 [details] 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.
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). $ xrandr --prop Screen 0: minimum 320 x 200, current 1920 x 1200, maximum 8192 x 8192 LVDS1 connected (normal left inverted right x axis y axis) EDID: 00ffffffffffff0030ae104000000000 26120103801a1078eae59593564f9028 28505400000001010101010101010101 0101010101016a1d00e850201e301030 220005a310000018261700a050201730 3020360005a3100000180000000f0081 0a3c810a3216010030640055000000fe 004c5444313231455756420a2020007a BACKLIGHT: 0 (0x00000000) range: (0,15) Backlight: 0 (0x00000000) range: (0,15) scaling mode: Center supported: None Full Center Full aspect 1280x800 60.0 + 50.0 1024x768 60.0 800x600 60.3 56.2 640x480 59.9 VGA1 connected 1920x1200+0+0 (normal left inverted right x axis y axis) 519mm x 324mm EDID: 00ffffffffffff0026cd015601010101 251201036c342178ea5ad5a7564b9b24 135054bdef80714f81908180818ca940 b300950f9500283c80a070b023403020 360007442100001a000000ff00303537 34323833373531383035000000fd0038 4c1e5311000a202020202020000000fc 00504c423234303357530a2020200050 1920x1200 60.0*+ 1600x1200 60.0 1680x1050 60.0 1280x1024 76.0 75.0 72.0 60.0 1440x900 75.0 59.9 1152x864 75.0 1024x768 75.1 70.1 60.0 832x624 74.6 800x600 72.2 75.0 60.3 640x480 72.8 75.0 66.7 60.0 720x400 70.1 HDMI1 disconnected (normal left inverted right x axis y axis) DP1 disconnected (normal left inverted right x axis y axis) HDMI2 disconnected (normal left inverted right x axis y axis) DP2 disconnected (normal left inverted right x axis y axis) DP3 disconnected (normal left inverted right x axis y axis)
I frigged around with the cable: pulling it in and out repeatedly, while suspending and resuming.

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.
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. $ xrandr --prop Screen 0: minimum 320 x 200, current 2304 x 800, maximum 8192 x 8192 LVDS1 connected 1280x800+0+0 (normal left inverted right x axis y axis) 261mm x 163mm EDID: 00ffffffffffff0030ae104000000000 26120103801a1078eae59593564f9028 28505400000001010101010101010101 0101010101016a1d00e850201e301030 220005a310000018261700a050201730 3020360005a3100000180000000f0081 0a3c810a3216010030640055000000fe 004c5444313231455756420a2020007a BACKLIGHT: 15 (0x0000000f) range: (0,15) Backlight: 15 (0x0000000f) range: (0,15) scaling mode: Full supported: None Full Center Full aspect 1280x800 60.0*+ 50.0 1024x768 60.0 800x600 60.3 56.2 640x480 59.9 VGA1 connected 1024x768+1280+0 (normal left inverted right x axis y axis) 519mm x 324mm EDID: 00ffffffffffff0026cd015601010101 251201036c342178ea5ad5a7564b9b24 135054bdef80714f81908180818ca940 b300950f9500283c80a070b023403020 360007442100001a000000ff00303537 34323833373531383136000000fd0038 4c1e5311000a202020202020000000fc 00504c423234303357530a202020004e 1024x768 60.0* 800x600 60.3 56.2 848x480 60.0 640x480 59.9 HDMI1 disconnected (normal left inverted right x axis y axis) DP1 disconnected (normal left inverted right x axis y axis) HDMI2 disconnected (normal left inverted right x axis y axis) DP2 disconnected (normal left inverted right x axis y axis) DP3 disconnected (normal left inverted right x axis y axis)
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
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.
