the graphic card is an intel 855GM However I could get a great resolution on my 19inches LCD ( with wich I made the install) but when i moved to a 17 inches CRT I can't go to anything than 640 * 480
How to tell Xorg ? I tried to add mode to xorg.conf but it's still telling the mode is not supported .
Shall I use 915 resolution ? is this problem specific to slitaz ? it seems to me it's a basic linux problem in fact
Try running tazx to reconfigure X. What has probably happened is there isn't a HorizSync or refresh entry in the Monitor section of etc/X11/xorg.conf. They are required by your crt. If tazx doesn't work see if you can get the specs for your crt monitor and make the entries in xorg.conf manually.
