Description Victor Hahn 2011-07-18 13:06:20 UTC
Fedora 15 does not recognize my VGA monitor, a LG Flatrom L1811S. In GNOME display settings it is listed as "Unknown" and setting a resolution higher than 1024x768 is not possible (native resolution is 1280x1024).

Current Ubuntu has the same problem, so this is probably an Xorg upstream bug or something.

Debian Lenny - or in fact any legacy distribution I remember - had no such problems with my monitor.

I was not quite sure which component this bug belongs to. Please correct as necessary.

Comment 1 Elad Alfassa 2011-07-18 16:36:21 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 add drm.debug=0x04 to the kernel command line, restart computer, and attach

* your X server config file (/etc/X11/xorg.conf, if available),
* X server log file (/var/log/Xorg.*.log)
* output of the dmesg command, and
* system log (/var/log/messages)

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 8 Victor Hahn 2011-07-21 16:52:52 UTC
Here's the requested data. dmesg output looks interesting - claims EDID checksum is corrupt...

I just spent some hours creating a working xorg.conf for my monitor. You'll find several xorg logs attached: one from my working Debian xorg (monitor autodetection), one from vanilla Fedora (autodetection failed) and one after I threw in manual configuration.

Comment 9 Fedora End Of Life 2012-08-07 14:44:49 UTC
This message is a notice that Fedora 15 is now at end of life. Fedora
has stopped maintaining and issuing updates for Fedora 15. It is
Fedora's policy to close all bug reports from releases that are no
longer maintained. At this time, all open bugs with a Fedora 'version'
of '15' have been closed as WONTFIX.

(Please note: Our normal process is to give advanced warning of this
occurring, but we forgot to do that. A thousand apologies.)

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, feel free to reopen
this bug and simply change the 'version' to a later Fedora version.

Bug Reporter: Thank you for reporting this issue and we are sorry that
we were unable to fix it before Fedora 15 reached 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, you are encouraged to click on
"Clone This Bug" (top right of this page) and open it against that
version of Fedora.

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:
