hello folks,

i hope someone can help me with the following problem.
I wanted to switch the OS from Win Xp to Mandriva Linux for my living room PC. The PC is connected to a about 15 years old TV screen .
With WIN xp i had no issues getting the Screen to work but now with Linux as i switch to KDE the screen starts to flicker and to scramble.
I cant see anything , cant even shutdown.
I tried all the Monitor presets but nothing made it to work.
Theres now just the option to enter the H and Vsync manually.

someone here knows what values i have to enter there ?
I cant find any info on the net and i have no manual for the TV.

Thanks in advance for any help.

what graphics card are you using? Try setting the resolution to 640x480@60Hz.

Ati 9500 and i allready tried that resolution,doesnt work
I guess its the frequency that matters not the resolution.
Win XP worked fine with 1024 800 and 640.

Are you running in dual head mode, or only a TV? Is you're TV PAL, NTSC, or SECAM? Make sure you have the correct format set. You're using the TV-out on the card right, not some weird scan converter box? TVs are standard not like monitors, different syncs are not used.

iam on single head mode from the svhs exit Pal.
i can work in the bash with it just kde doesnt work.
so i guess on kde something with the res, freq or something else changes the tv cant handle.
