Forced to use nomodeset and Intel VESA driver
Information to problem is below.
This problem I have experienced beginning with 9.04, at that time Samsung monitor and Matrox graphic card. Now using Intel HD3000 onboard graphics with same monitor. Do not understand why monitor is seemingly not being recognized and why the Intel VESA driver is being used. In addition, computer does not awake from standby. Inasmuch as now at 12.04 I would like to have this problem solved and then not upgrade for a while. Have looked around but found no answer aside from fooling around with xorg.conf. EDID appears to be correct, but xrandr not. Any assistance appreciated.
