So if you allow people to screw with the OS, they will break it, and I did.
I installed Ubuntu 10.04 32 bit on an intel dual core 2.9 Ghz with 8GB ram and 2TB disk. It was running great, and I set about customizing the desktop and installing apps. 4 days later, I was very happy with the entire setup.
I noticed that there was a proprietary driver available for my graphics board. So I had the suggested driver downloaded and installed.
A reboot later, and my monitor says it doesn't support the input frequencies, and there is no desktop display after I log in. The login runs, the desktop does not.
So, just because my video board supports something like 3k x 2k resolution, why does that have to be the default display resolution?
I can run the live CD and mount the disk File Sys, but can't find where to set the default resolution for my desktop. I have a Samsung 37" flat screen LCD TV for a primary monitor, as well as 3 models of Viewsonic 19" flat screen monitors. None can display what the video board is cranking out. (The Samsung makes an awesome monitor!)
Xorg.conf is not the file to edit. I can't find the video driver to delete, and I can't get the OS to boot with a usable GUI display. I can't seem to boot to a command line either.
Solutions could include: How to boot to a command line and not a GUI desktop (maybe something like windows "safe" mode.) What file to edit to set the default display resolution to something more sane, or possibly something I have not considered yet.
I have researched this in 4 separate Ubuntu books, but none of them seem to talk about this topic at the depth I need or suggest ways to recover.
Setting the display resolution in a live boot distro does not appear to touch the OS on the hard drive (no surprise), so I need to hand edit something on the HD.
Please point me to the proper file to edit to get my GUI back.
My fallback position is to wipe the hard drive and re-install at the cost of a week or so in total setup time. I have 370GB of MP3 files it takes the better part of a day to load. 2TB is a great disk size until: You need to back it up; you need to check the file system; you need to re-install an OS.
I also don't know why I can't just "upgrade" back to the original 10.04 install from the live CD. It is not an option though. It will install a 2nd copy alongside the 1st (not really useful to me), and it will delete everything and set it all up fresh and new. I would like to keep my partitioning and simply re-install the OS, hopefully retaining my installed applications. Using "custom" partitioning does not seem to pick up the "root" partition. I can't seem to re-install to the existing partition scheme.
If this is not enough I have recently purchased a Palint GTX460 2GB video board. The default power on resolution (sans driver) is not fine enough (640x480) to allow me to access the administrative "get proprietary driver" menu. I could delete most of the icons in the top toolbar to get access to the system drop down menu. I suppose I could just install a fresh OS copy with this board installed, but I hate to lose all my work to date.
This board is not the one I am currently having problems with, I am just fishing for advice on future problems with the GTX 460 2GB.
Clearly I need a crash course in configuring X11 from the command line.
Any help / advice is much appreciated. Email me is fine.
