This is lenovo laptop running XP with Intel 945GM GPU. The display setting jumpped to 640x480 4nit color after reboot. The options in the display setting tab are correct, but if I change them, it always jumps back to 640x480 4 bit right away. I've removed/reinstalled video driver many times. Intel driver works fine except that the settings can't be changed. If I remove Intel driver and use XP'
s default one, the settings can be changed without a problem. Once I reinstall Intel driver, the settings are locked. Logmein had been used on this box, removing it didn't solve the problem.
Thank you in advance!
