A problem with my computer graphics mode. Before the low graphics problem , whenever I entering into GUI I see an error as " app armor intialization : LSB " which goes off in seconds and then I will get GUI login as usual. after the usual login, I checked my SE linux status which is in permissive mode, early it was in enforcing mode. but after making it in enforcing mode, low graphics mode error started to occur.
four options I got,
1) try to start with normal graphics mode 2) Reconfigure 3) troubleshoot error 4) exit to console login.
1st option starts the process again to low graphics mode.... it does nothing
2nd option reconfigure takes me to two set of options
2a) generic system 2b) backedup config
both does nothing .. not even a react
3rd option troubleshoot error takes me to 3 option
3a) show startup error 3b) show error log 3c) seriously I forgot the 3rd option in this issue.
but those 3 also doesn't react a bit.
4th option exit to console login
4a) goes to tty1 login... but when i tried to enter with correct username and password, console logouts immediately with a second
After the lot of searching,
I updated graphics driver from Xorg video-intel .. but ubuntu said graphics is updated.
when i tried to look /etc/X11/Xorg.conf .. actually there is no file exist so i created it with some commands from stackover flow..
Now that file also doesn't exist. Instead it has a file called xorg.conf.failsafe
and that file has the following thing
Section "Device" Identifier "Configured Video Device" Driver "fbdev" EndSection Section "Monitor" Identifier "Configured Monitor" EndSection Section "Screen" Identifier "Default Screen" Monitor "Configured Monitor" Device "Configured Video Device" EndSection
Now I installed GDM . now its prompting me to use single display manager program. I am waiting to press okay for it, still didn't press it.
And this is my lscpu
