Install video card on Lubuntu with NVIDIA chipset
Install video card on Lubuntu with NVIDIA chipset
I bought a new video card the other day from Zotac and I figured I would install the drivers via their website or the NVIDIA website (a downloadable file named NVIDIA-Linux-x86_64-###.##.run). WRONG!
The best way to install NVIDIA drivers is through the official Ubuntu repositories:
sudo nvidia-installer --uninstall
sudo apt-get remove nvidia* --purge
sudo update-initramfs -u
sudo apt-get install nvidia-current
For most people, that should be sufficient -- reboot and verify. If the resolution still looks off, read on...
It turns out I had black bars at the top and bottom of my screen and everything was fuzzy. It turns out the NVIDIA auto-configuration didnt detect my old monitor (SyncMaster 920nw) and its weird 1440x900 aspect ratio so I needed to do some additional tweaking.
I ran this command to generate my /etc/X11/xorg.conf file (bypassing automatic monitor detection):
sudo nvidia-xconfig --no-use-edid-dpi
I then edited the /etc/X11/xorg.conf file and added the following line to the Monitor section:
Option "DPI" "96 x 96"
I also had to change the HorizSync and VertRefresh values to (check your monitor manufacturer page to find the right values for your monitor):
HorizSync 28.0 - 80.0
VertRefresh 48.0 - 75.0
Then, in the Screen section, I had to add:
Option "IgnoreEDID" "true"
After saving the file, I rebooted and loaded the NVIDIA config tool (Start > System Tools > NVIDIA X Server Settings). In the X Server Display Configuration screen, I clicked the Resolution dropdown and chose 1440x900. Once the resolution updated and looked good, I clicked the Save to X Configuration File button.
After rebooting to verify the change persisted, I had to update my /etc/default/grub file with these lines to improve my splash screen and grub list resolution:
GRUB_GFXMODE=1024x768
GRUB_GFXPAYLOAD_LINUX=keep
(note: my BIOS video driver doesnt support 1440x900 so I just went with a decent alternative for my needs. Feel free to run sudo hwinfo --framebuffer to check your options)
In addition, I needed to create/update the /etc/initramfs-tools/conf.d/splash file to add this line:
echo FRAMEBUFFER=y
Finally, I ran these commands to apply the changes:
sudo update-initramfs -u
sudo update-grub2
I rebooted once more to verify the grub list and Lubuntu splash screen at startup looked moderately better.
...Hope this helps anyone else with an unusual setup like mine!
