I have a CentOS 5.3 Desktop and use Evolution to read mailing lists . When i move from one read letter to another(either deleting or clicking next the Message pane flickers. How can i stop this because it is hard on my eyes when i have a few emails to read?
Increase the scan frequency of your monitor maybe? I've seen this in
lists
generally with thousands of entries and the gfx-card can't keep up. Most often upping the scan frequency solved this issue. I've also seen this on computers that are a bit, ummm, underpowered. ;-)
If you have an Nvidia gfx-card, try installing the proprietary drivers,
or
(recommended) dkms and the dkms-Nvidia*-package.
YMMV.
Thanks for the reply. My card is a GeForce FX5200 is there an easy way to set it up as there seem to be a few options? Not sure how to increase scan frequency? is it dangerous?
Did you install either the dkms-Nvidia-package or the proprietary Nvidia driver package? Shouldn't matter anyway, as both install a "Nvidia X Server settings"-applet. With this you can change resolutions, scan frequencies and whatnot.
Dangerous? Well, yes. If you set too high a frequency you might damage the monitor. For flatscreens the most common frequency is 50 (older standard IIRC) or 60Hz (most common nowadays). CRT's can vary between 60 to 120Hz. Most common AFAICT is the 75-85Hz range.
Your flickering thing might also be because of a too high set screen resolution. Start with 1024x768 and 75ish Hz and go up stepwise. See if it gets better. -- /Sorin

I installed the dkms but i couldnt make it work so its back to nv driver now. My resolution is the same as i have been using for years on this monitor and seems to work well. I have now installed Claws mail and the message pane jumping problem has vanished Thanks for your help. Jeff
