Red Hat Bugzilla – Bug 188582
Problems setting resolution on external monitor of a laptop
Last modified: 2018-04-11 07:11:08 EDT
Description of problem:
I have the IBM Thinkpad T40 laptop installed with FC5 and Windows XP. The
internal LCD screen is capable of 1024x768 resolution. The laptop is docked onto
a docking station with external monitor attached. The external monitor is
capable of 1280x1024 resolution.
On Windows XP, I'm able to set the resolution of the external monitor to
1280x1024. This was also the case for Fedora Core 4.
Now, with FC5, I can't seems to set the resolution of the external monitor
higher than 1024x768 (as the internal LCD screen).
IBM Thinkpad T40, Type-model 2373-7CG
ATI Radeon Mobility M7 LW
Version-Release number of selected component (if applicable):
Fedora Core 5
Steps to Reproduce:
1. Put the Thinkpad on the docking station
2. Boot into Linux
3. Set the resolution to 1280x1024 (in /etc/xorg.conf)
The resolution of the external monitor stays at 1024x768
External monitor set to 1280x1024
This seems to be a regression in the upstream radeon driver's display

Reporter, are you still interested in this bug? Have you filed that upstream

If you won't be able to reply in one month, I will have to close this bug as
INSUFFICIENT_DATA. Thank you.
Fedora Core 5 is no longer supported, please, could you reproduce this bug with

Fedora 7, or Rawhide)? If this issue turns out to still be reproducible, please
let us know in this bug report. If after a month's time we have not heard back

Setting status to NEEDINFO, and awaiting information from the reporter.

xorg-x11-drv-ati has dynamic external monitor support as of 6.7.191. Fedora 8
will include this support out of the box.
