If you have the kernel source, have a look at the file Documentation/fb/intelfb.txt
Thanks for your reply. I added video=intelfb:1200x800-32@85 to my boot line in grub. As a result the vertical frequency increased from 60Hz to 70Hz, but not 85Hz. Also the screen resoltion did not change but stayed 800x640. I added 'vga=790' (for resolution 1024x768x256) to the above. Then the resolution changed accordingly but the frequency turned back to 60Hz. I also experimented with other resolutions which i saw in intelfb.txt, but the monitor frequency never goes over 70HZ and i cannot have both high frequency (70Hz) and high resolution (anything other than 800x640).
Do you know if I can have both vert. freq. 85Hz and console screen resoltion 1024x768 for video chipset Intel 845G and monitor Dell GX260?
