Toshiba Satellite Pro 4600 dual boot XP Pro & Hardy. Video card is Trident Microblade/XP which uses Intel 80815 chip. Upgraded to Intrepid (kernel 2.6.27-7 generic). Lost 1024x768 resolution a few upgrades back. Tried sudo displayconfig-gtk: command not found. Then gksudo gnome-display-properties but nothing happens.
System>preferences>screen resolution gives a pink "unknown" square, 800x600(4:3), 60 Hz. System>Administration>Hardware Driver gives "no proprietary driver detected in this system". This is strange because in Hardy, the system has both "ati_drv.so" and "trident_drv.so". I gather these are driver files that gave 1024x768 resolution.
I suspect somehow the existing Trident driver was not recognized by the new Xorg that comes with Intrepid. How do I find "xserver-xorg-video-trident" which is supposed to be in Intrepid, and how can I install or reinstall this (new?) driver? Could you help me regain 1024x768 video resolution? Thanks kindly.
