I googled The EDID read for display device CRT-0 is invalid This got me to someone who got a response out of a knowledable expert... So suddenly I understood my problem. Apparently Xorg goes very conservative if it doesn't ID the monitor. (Why it used to, and then not anymore, is probably nvidia driver's doing) So adding HorizSync 31.5 - 90.0 VertRefresh 60.0 - 60.0 to my xorg.conf file made Xorg less paranoid, and displayed my resolutions as I needed it. *sigh* (of relief).

(50 times? more?) Anyway, here is my tale, and I hope that someone could help me! I always had an on-board intel graphics card, which well... was ok, but kinda struggled with games. So I got a 2nd hand 3d card off <a href="http://gumtree.co.za" target="_blank">gumtree.co.za</a> which happens to be nvidia fx 5500 AGP. My pc is still old enough, so it had AGP slot. Everything worked great! I slotted it in, and when the PC rebooted, I got a lovely 2048x1536 resolution (on my 21" monitor - CTX - don't really know the brand), which high refresh rate. Awesome! My 3d games first pass worked (Half Life 1 - Counter strike, Open Arena, and some others). However... Starcraft ran hugely slow. 2-3 fps. I couldn't follow my mouse cursor, it was so slow. Played around with settings (wine regedit current user directdraw = "opengl" or "gdi" etc.), which needed reboots - Starcraft didn't play well... So, I checked for updates. Yes! Nvidia updates, as well as a kernel update, as well as wine! Cool! Ran updates, and restarted (for kernel). When I had to log on, I was greeted with a 640x480 login screen where the e's of my name didn't have a little hole... Since then, well I haven't been able to use the PC, I have just been trying to fix it. I've done several stuff... (in no particular order): * sudo dpkg-reconfigure xserver-xorg * installed new drivers, old drivers, vesa drivers (I got 800x600 with them) * uninstalled all nvidia drivers * added resolutions to /etc/X11/xorg.conf (and other xorg.conf edits and attempts) * added some modules not to be loaded in /etc/default/linux-restricted-modules-common * Xorg -configure (from a non graphical shell) * rebooted in recovery mode, asked to try to fix X * played around with envyng Some of the symptoms: * My monitor is crt-0, where it used to have some name (can't recall what) * dmesg | grep nvidia outputs: [ 16.402126] nvidia: module license 'NVIDIA' taints kernel. [ 17.057709] nvidia 0000:01:00.0: PCI INT A -> GSI 21 (level, low) -> IRQ 21 * glxinfo | grep render outputs: direct rendering: Yes OpenGL renderer string: GeForce FX 5500/PCI/SSE2 * xrandr outputs: Screen 0: minimum 320 x 240, current 1024 x 768, maximum 1024 x 768 default connected 1024x768+0+0 0mm x 0mm 640x480 50.0 52.0 320x240 51.0 1024x768 52.0* (note: the 1024x768 is a "panning" setting used to at least be able to use the PC, the monitor is still at 640x480) * lshw -C video outputs: WARNING: you should run this program as super-user. *-display description: VGA compatible controller product: NV34 [GeForce FX 5500] vendor: nVidia Corporation physical id: 0 bus info: pci@0000:01:00.0 version: a1 width: 32 bits clock: 66MHz capabilities: bus_master cap_list configuration: driver=nvidia latency=248 maxlatency=1 mingnt=5 module=nvidia I'm not a linux expert, and I've tredded in waters and places many an expert hasn't gone yet. No avail. Why can't they make 3d capable open source drivers?! So now, even if I try to get back onto vesa drivers I'm stuffed. I could still go to my intel on-board, but even that doesn't reach the same resolutions it used to in the past. How did nvidia screw up my PC so badly? Sorry, I am truely frustrated... could someone give me a similar experience with a better result?
