Odd problem with LCD on FC4

smoker · 09-12-2006, 04:14 PM

Hi,
I just swapped my 19" crt over to a Dell 19" TFT. I had to mess around with /etc/X11/xorg.conf to get the refresh rate acceptable to the monitor, but at the moment it is running ok. Except .....

There is an area which covers around 10% of the screen in a vertical border on the far left hand side. I cannot drag any desktop icons to this area ( they spring back). I can drag a window over this area and it stays there, but if I maximise the window, it won't cover that 10% of the desktop. Strangely, terminal windows WILL cover the full 100% when set to full screen, as will firefox, just not when maximised.

The taskbar is located on the bottom of the screen and it covers 100% width ok and the desktop picture is covering 100% too.
I've checked for inconsistencies in xorg.conf but can't find any. I am running the nVidia binary NVIDIA-Linux-x86-1.0-8762 and this installed ok and GL runs fine.
I'm on kernel 2.6.17-1.2142_FC4 and that runs fine, no issues.

I'm thinking that maybe there is an issue between xorg.conf and the window manager (Metacity) but have no idea where to start looking.

Has anybody any ideas, or suggestions ?

TIA

And what are the default Horizontal and Vertical rates for the Dell 19" TFT???? Check the manual.

Try running the system-config-display and see if this Dell 19" TFT if listed, if not then select the Generic 1280x1024 Flat Panel Display. Or as root try something like;

init 3
(You might have to press the 'Enter' key a few seconds after the last service restarts)

cp /etc/X11/xorg.conf /etc/X11/xorg.conf.mybackup

Code:

system-config-display --reconfigure --set-resolution=1280x1024 --set-depth=24 --set-driver=nvidia

The above command reconfigures your /etc/X11/xorg.conf file NOT based on your current xorg.conf configuration file, sometimes this corrects anything that is not quite right. The xorg.conf.mybackup file is created so you have something to go back to just in case something goes wrong.

Check the /var/log/Xorg.0.conf file for additional clues and information.
