Hey gang, I hope this question has a lot more meat on its bones as Ive learned a great deal about altering the video parameters that are being fed to the kernel. Problem: On my mobo the integrated video card (a via chrome9 based card) and monitor (an old Samsung SyncMaster 955DF) Fedora 9 cant figure out what video combination to use and when it screws up, it locks up the system tight. Only a hard boot will fix it. On an install cd anaconda will accept the xdriver=vesa option and graphical install works fine, The only real issue is that in my experience Anaconda notoriously uses low resolution so as to hide problems with a video setup till the actual system is installed. So taking what I know and applying that to a LIVE CD (specifically the KDE one, as Im a KDE guy and dont have much use for Gnome, etc (please no flames, is a personal preference, I didnt - and wont - say gnome sucks - it doesnt, just that I dont like it.) OK, the Live CD doesnt have anaconda on it (nor should it) but I need a way to apply what Ive learned about telling the system to use VESA till I can figure out the details of why my hardware is not working corectly. First, the kernel will accept a vga=xxx code that affects the terminal consoles, but that doesnt seem to have any affect on X. The kernel command line can be altered by adding something like "video=vesafb:mode:1280x1024-75" This seems to really help my situation, but not enough. without this alteration the LiveCD will crash and lockup hard within 5 seconds or so after udev starts. with this alteration the LiveCD boots successfully and displays a login prompt (which is further than I ever got before) but the keyboard is still locked and about 5 seconds or so later I get a funny horizontal image on the screen that is indicative of overstating the capability of the video hardware at some level. I know I'm on the right track here, but I cant seem to finish the job, any help much appreciated. I need a hint or a pointer to let me know what Im missing please. Thanks all
The only clue that I can offer is that X for the live CD supposes that the "magic" for auto-detection will work without an /etc/X11/xorg.conf file. As you realize, it is a poor "magic show" for your hardware.
Booting in runlevel 3 and transferring your working xorg.conf file before telinit 5 should get X working without attempting auto-detection.
Since I did not try the live CD myself, going to the fedora installation on-line help sites for live CD's that should exist out there somewhere.
