mount error(1)
After reinstalling ubuntu 10.04.3, I couldn’t remount to the share drive unless using sudo. I kept getting the error message: mount error(1): Operation not permitted. After a little bit digging, this post solved the problem perfectly!
Reinstalling GRUB
Lots of post mentioned that before. I recently reinstalled Ubuntu and I had three drives in my computer. After installation, I wanted to remove one of the drive since it appears that the system was extremely slow and unstable with all three drives plugged in. I suspect that it was a power problem since I had a power hungry NVidia video card installed also.
Unfortunately, GRUB was not installed in the “right drive” but exactly the drive I wanted to remove. Anyway, the command to save the day is
dpkg-reconfigure grub-pc
Just run it after getting into Ubuntu.
Ubuntu installation on nvidia computer
My harddrive died recently and so I reinstalled ubuntu. I got fed up with new release breaking tiny things often. So I tried to stick with LTS this time (10.04 when I wrote this).
I have an NVidia graphic card and dual monitor. I recalled troubles already from my previous experience of installing Ubuntu. I was sorry that I didn’t drop down some notes. This would have saved me lots of time.
First, desktop installation CD doesn’t work because of the video driver problem. It actually can’t even boot to the installation screen (more video problem discussion later on).
So I tried the alternate CD. But somehow ubuntu kept complaining the disk was bad. Even though it passed the integrity test. After wasting two disks, I decide to use USB installation instead.
USB installation is okay. But then I still have problem with the video driver. The system was “frozen” (I could moved my mouse) after I tried to login. I finally was able to get into Gnome through failsafe graphic mode (select recovery in Grub and then failsafeX in recovery menu). After get into Gnome, pick Hardware Drivers from Administration. After activating NVidia driver, I finally was able to get into Gnome in normal mode.
