Installed wrong nvidia driver, help me find correct boot options. Debug info inc.
I mucked my system up while trying to install proprietary nvidia drivers -- I was careless and installed the wrong ones (should have used legacy drivers). Now my system hangs on "starting udev" during boot.
I have tried many combinations of boot options in an effort to blacklist the problematic driver. Attached is a picture of my boot screen after specifying the options "single init 3 modprobedebug", and removing the options "rgbh quiet". For some reason I am having a lot of trouble blacklisting the correct module, or maybe I caused a kernel problem, which in that case is beyond me.
Also, boot option syntax question: can I specify something like "rdblacklist=*nvidia*" using wildcards?
thanks in advance.
I'm not exactly an expert, but I've mucked up nvidia driver installations before. Here's what I did on Debian--
-At the GRUB screen, selected to boot into recovery mode, which gives me a CLI-only environment
-Use nano or vi/m to comment out all the lines in xorg.conf, or simply rename the file to xorg.conf.bak
The default video driver (I believe it's nouveau or vesa on Ubuntu??) will be activated.
I don't have GRUB installed on this system, as it only has single OS. Instead of getting a GRUB menu, it just starts to load the kernel right away. If I could find a way to reach a command line/text editor that would be great, but at this point I cannot even boot into single user mode. The previous module used was nouveau.
What is the graphic module you used now?
Edit the /etc/modprobe.d/blacklist.conf file, add a line:
Maybe it will help.
Grub is sometimes hidden on single os systems sometimes.
Use a rescue cd.
Edit the /boot/grub/grub.conf these lines:
Set timeout=seconds and add # in hiddenmenu lines.
