ubuntu again with problems

i had installed ubuntu on my computer again. it was third times that i installed it. why i installed it again? i think my old ubuntu is dirty so i think i will install it again for new version, 7.10 (my old one is 7.04).

after i had finised it, i restart computer and found the problem. "video mode not supported". and it not boot my new ubuntu. i searched the internet and think that the new ubuntu don't support my vga card. but when i press ctrl + atl + f1 for use command line, it can boot my ubuntu and can use it regularly. so i tryed to install nvidia vga driver.

• sudo apt-get install nvidia-glx

but it couldn't install. why? why? why? i didn't know. so i went to look my repository(sourecs.list) with "software sources" application and i found that nothing was selected. so i selected it all. now i can use "apt-get install".

but i don't sure that command "sudo apt-get install nvidia-glx" is correct so i go to system -> prefernces -> apperance -> visual effects, i remember that if i choose to use visual effects and my computer doesn't have vga driver it will install automatically.

so i have vga driver. i restart my computer with happy but it still have same problem, "video mode not supported" : (. and i had no idea how to fix this problem so i decided to post my problem on ubuntuclub and pantip

next day, there was man answered my question(thank you very much). solution is that i must change /etc/usplash.conf to become 1024x768 and add "vga=791" after kernel in /boot/grub/menu.lst and use command

• sudo update-initramfs -u -k `uname -r`

so my problem was solved. and i can use ubuntu happily
