I've been tidling XF86config for 8 years now on my DELL Latitude XPi 90ST to find the right setting that would synchronize correctly with the LCD and avoid that ugly stuff. The only way I found up to now was to avoid white and other very bright colors, and of course, no gray pattern. At least I'll be able to get a neat picture on my LCD! Thank you very much! (Of course, since I never hook any CRT on my laptop, I never had a reason to switch the LCD/CRT mode...). Thanks a lot. > toggle back to the LCD, and with the LCD enabled, type 'startx,' X > comes up fine on the LCD (which it has for years).
