Unless one properly utilizes TRIM and uses an optimized OS for a SSD, one can go bad in less than a week (my experience with cheap MLC non-SandForce 64G OCZ and Corsair SSDs). All you need is a program that uses block based access to the SSD and "touches" the same block many times per second (in my case a ionode benchmark). And the SSD went 5 feet under REALLY fast.

Working for me with 1920×1200 resolution with a cheap KVM (announced to work for 1920×1440 VGA resolution)

1. Get a working xorg.conf file for your system using whatever method
2. Get in a terminal the modeline corresponding to your monitor and desired resolution using :
gtf 1920 1200 60
(in my case, first param for the width, 2nd for the height and 3rd for the freq… on new computer you should access these information in the menus from comuter)
3. Modify your xorg.conf :
Add the obtained modeline in the “Monitor” Section

Section "Monitor"
Identifier "Configured Monitor"
Modeline "1600x1200_75.00" 205.99 1600 1720 1896 2192 1200 1201 1204 1253 -HSync +Vsync
Modeline "1920x1200_60.00" 193.16 1920 2048 2256 2592 1200 1201 1204 1242 -HSync +Vsync
EndSection

in my case

Finally add the corresponding Mode with the same name as in the modeline in the Subsection Display of the section “Screen”


SubSection "Display"
Modes "800x600" "1024x768" "1600x1200_75.00" "1900x1200_60.00"
EndSubSection

Hope it can help…
