can't boot ubuntu....

[jgamez07]

Hi im a linux newbie, and i downloaded various live cd's, all had the same problem, the cd would start then when it would load the kernel the screen would go blank and my tv would say mode not supported, i searched a lot of forums and figured out, i had to start in safe graphics mode. I was finally able to get ubuntu linux to load and I installed it, however when it finished installing it booted up the blank screen again...i figured i would try to boot the live cd and see if i could install the right graphics drivers. Now none of the live cd's will let me change the options, the timer is stuck on 0s when the cd asks to pick the language...i tried many different distributions all with the same problem, except for open suse. open suse does not even show a timer it just says loading kernel. how can i fix the live cd's ive tried downloading new ones all with the same problem, the kernel loads without letting me press f6 to change the modes....? Or is there a way i can install the graphics drivers in recovery mode

my graphics card is a radeon hd3850...

Hi and Welcome !

I was finally able to get ubuntu linux to load and I installed it, however when it finished installing it booted up the blank screen again...

Have you removed Ubuntu or is it still installed? Is machine booting up in Command Line Mode?

[jgamez07]

yes i still have it installed, and i just figured out how to get to the terminal on recovery mode but i don't know what to do from there

[devils casper]

Execute this in recovery mode :

sudo nano /etc/X11/xorg.conf

It will open xorg.conf file in nano editor.
Add Driver "vesa" in Video Card section. In case there isn't any Video Card section, create new.

Section "Device"
    Identifier    "Configured Video Device"
    Driver        "vesa"
EndSection

Press Ctrl+X, Y and hit Enter key to save file.

Execute this to reboot machine :

sudo shutdown -r now

If Graphics work fine ( it will be minimal though ), I will post instructions for ATI driver installation.

Does your machine has internet access?

[jgamez07]

yes my computer does have internet access...i connected the onboard graphics card, and installed the drivers, and now the ati graphics card does boot...how can i ensure i have the right display drivers for my graphics card...i think the drivers its using are for the onboard graphics card...

[devils casper]

Execute this

sudo lspci | grep -i vga
grep -i driver /etc/X11/xorg.conf

Post output here.

You have installed right driver. Are you having any display problem?

[jgamez07]

no the display just seems a bit jerky, thats all...the prob i am having is with the sound drivers, i can't find the sound blaster xfi drivers for linux
