Red Hat Bugzilla – Bug 468793
Unable to split screen between multiple monitors of different aspect ratios
Last modified: 2018-04-11 07:23:38 EDT
Description of problem:
It seems that multiple monitor doesn't work properly between monitors of different aspect ratio. I am running rawhide on a Dell Latitude X-1 (12" widescreen) and attempted to hook it up to a Dell 1503FP (15" 4:3). The monitor was recognized but with current resolution (1280x768) it doesn't turn on. I restarted Fedora and now both monitors work; the resolution was set at 1024x768. The aspect ratio applies to both monitors, however, and the screen was stretched on the laptop monitor (appear normal on the external monitor). I cannot unsplit screen.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Hook up laptop to external monitor while Fedora is running.
2. Then restart and compare.
I expected xorg to be able to differentiate between the two aspect ratios and allows me to extend the desktop to the external monitor. I'm not sure if this is achievable by default, though.
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) and X server log file (/var/log/Xorg.*.log) to the bug report as individual uncompressed file attachments using the bugzilla file attachment link below.
Could you please paste in the comment output of the command
We will review this issue again once you've had a chance to attach this information.
Thanks in advance.
I have exactly the same issue : a laptop widescreen and a 19" monitor (4:3).
I cannot split the desktop, and if I use gnome-display-property, my second monitor is detected as "laptop" (and my laptop screen too), even if I unselect the "clone" mode.
I will provide the output of the commands asked by Matej Cepl latter today.
(for now : I can just say that I DON'T have any /etc/X11/xorg.conf file. It's a brand new fedora 10 install)

X log files
there were 6 different logs, they are all collapsed in one file.
I'm not the reporter, but I have exactly the same issue, so here are the additional informations you wanted:
$ xrandr -q
Screen 0: minimum 320 x 200, current 1280 x 800, maximum 1280 x 1280
VGA-0 disconnected (normal left inverted right x axis y axis)
LVDS connected 1280x800+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
(see attachement for the X server log)
(and I haven't any xorg.conf file)
Reporter, could we get that xrandr -q output, please?
It would be interesting to get the output of
both when the screens are plugged in and when they are not.

Sorry. I've been busy for the last few days.

Log for Xorg
This bug appears to have been reported against 'rawhide' during the Fedora 10 development cycle.
Changing version to '10'.
More information and reason for this action is here:
This message is a reminder that Fedora 10 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 10. 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 '10'.
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 10'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 10 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 10 changed to end-of-life (EOL) status on 2009-12-17. Fedora 10 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.
