I have tried purging the nouveau driver, putting it in blacklist, using ppa:graphics-drivers, (I tried one such oibaf:graphics-drivers), downloaded the 304.137 driver from Nvidia, tried
ubuntu-drivers autoinstall and neither of them worked. The only result was that I saw the screen at 640x480.
Using the command
sudo apt install, the following results appear:
$ sudo apt install nvidia-304 Reading package list... Done Creating Dependencies Tree Reading status information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: nvidia-304 : Depends: xorg-video-abi-11 but is not installable or xorg-video-abi-12 but not installable or xorg-video-abi-13 but not installable or xorg-video-abi-14 but not installable or xorg-video-abi-15 but is not installable or xorg-video-abi-18 but is not installable or xorg-video-abi-19 but is not installable or xorg-video-abi-20 but is not installable or xorg-video-abi-23 Depends: xserver-xorg-core but it will not be installed Recommends: nvidia-settings (>= 331.20) but it will not be installed E: Unable to correct problems, you have held broken packages.
I don't know which tutorial to follow anymore. Can anyone fix this? It's a motherboard with an Nvidia nForce 430 chipset and IGP GeForce 6150LE.
