I'm new to Linux world, infact I have installed Ubuntu 12.04 yesterday on my computer. I have Dual-COre processor, 2GB RAM, 500GB HardDisk, No graphics card and XP in parallel. I'm facing So many problems in Ubuntu:
1) Login Screen is on left side and only half of it is visible.
2) I logged in with password which I had Set while installing Ubuntu but still it is showing me Guest-Hbicaz@ somthing
3) Sudo command is not working. When i tried to install gedit using this command
"sudo apt-get install gedit". It is giving me these errors
sudo: unable to change to sudoers gid: Operation not permitted sudo: setresuid() [0, 0, 0] -> [118, -1, -1]: Operation not permitted
I'm new to Ubuntu.
I have searched to solve the Login screen problem but I cant solve because sudo command is not working
