Description François Rossigneux 2008-02-03 13:14:40 UTC

Version:            (using KDE 4.0.0)
Installed from:    Gentoo Packages
OS:                Linux

The default resolution that KDE choose just after its install is 1152x768, but I want to have a 1024x768 resolution (to reach a 75 Hz refresh rate).
To fix this, I change my screen resolution in System Settings (and the change takes effect).

The problem is that KDE hasn't memorize this resolution :
- If I restart KDE, the old resolution is used.
- If I restart KDE and I open the Display System Settings, the screen automatically switch to the good resolution (although the screen size in the dialog box is 1152x768 !).
- I have remarked that if I re-open the Display System Settings just after to have applied my new resolution, it's always the old which appears in the window (although the screen stay in 1024x768 until I restart KDE).

I don't have this problem with KDE 3.5.7 or Enlightenment.
Thank you.

(and sorry for my bad english !)

The bug hasn't been resolved with the KDE 4.0.1 release.
There is an other person who has the same problem here : http://forum.ubuntu-fr.org/viewtopic.php?pid=1522402 (in french !).
Thank you.

Comment 2 François Rossigneux 2008-02-16 19:58:41 UTC

I have a message in the console when I open the Display System Settings page.
The message is :
systemsettings(28650): ""UnifiedRect" - conversion of "0,0,0,0" to QRect failed"
Thank you.

Comment 3 François Rossigneux 2008-03-22 12:16:10 UTC

I have resolved my problem by adding "Virtual 1024 768" in the Display SubSection of my xorg.conf.
I thought to have this problem only with KDE 4, but there is this problem on older versions of KDE too (but I havn't notice it because I was on an other distribution).
The bug, if it's really a bug, is in KDM...

Comment 4 Gregor B. Rosenauer 2008-08-09 10:42:00 UTC

I have exactly the same problem. I am using an external monitor with 1920x1200@60Hz connected to a Radeon X1300 in a laptop (Acer Travelmate 6463WLMi).
Adding the "Virtual" line does not help, and I have to open Display Settings everytime I login to restore the full resolution.
Maybe related to bug 163707
Using Kubuntu 8.0.1 x86 with KDE 4.1 final.

Comment 5 Jens Herrmann 2008-11-22 20:37:46 UTC

I had exacly the same problem and was able to resolve it by modifying the xorg.conf to "Virtual 1024 768" as suggested. Using Kubuntu Ibex AMD64 with KDE 4.1.1.
According to the comments in bug 157139 (https://bugs.kde.org/show_bug.cgi?id=157139), which is a duplicate of this bug, someone set the status to "resolved" before June 2008. How can that be when in fact this bug is present to this day?
