No desktop with nVidia video chips
This is a problem not only with the LiveCD, rendering an install virtually impossible, but on a freshly installed system as well. There is a known bug for this. The workaround is to create a configuration file for X as documented here, though this will only really help on an installed system.
NOTE: nVidia, Radeon, and ATI chips all display different behaviors. This workaround only applies to nVidia chips. If you are not sure what you have, you can boot into the system (even an old LiveCD will work) and issue the following command to see what video chip you have:
lspci | grep -i vga
If you do not see "NVIDIA," then don't expect this to solve your problem.
Here's the workaround:
- Use the alternate ISO to install, not the desktop.
- After the install, boot like normal. You should get to a black screen with some text on it. It appears frozen.
- Open a virtual terminal using the keystroke Ctrl-Alt-F1. You can use any F-key from 1-6. Note that on Apples this is more adequately described as Fn-Ctrl-Option-F1 since Fn-Option is Alt.
- Login with the credentials you created during the install.
- When at the command prompt enter the following commands:
sudo Xorg -configure sudo mv xorg.conf.new /etc/X11/xorg.conf sudo nano /etc/X11/xorg.conf
- and enter your password at the prompt.
Edit the file so that it looks like this and save it.
- Reboot with:
sudo shutdown -r now
as an alternate to steps 5 and 6, if you have Internet access, you can use the following command: sudo wget http://paste.ubuntu.com/1284325/plain/ -O /etc/X11/xorg.conf, which, of course, requires your password.
No desktop with Radeon video chips on LiveCD
Radeon will not boot to the desktop without a boot command on the LiveCD. You will need this for booting the installation media but once the system is installed, it is unnecessary. That means if you use the alternate installer, netboot, or something other than the desktop ISO, this is not needed.
NOTE: nVidia, Radeon, and ATI chips all display different behaviors. This workaround only applies to Radeon chips. If you are not sure what you have, you can boot into the system (even an old LiveCD will work) and issue the following command to see what video chip you have:
lspci | grep -i vga
If you do not see "Radeon," then don't expect this to solve your problem.
At the boot: prompt type:
where 1024x768 is your xy resolution, 32 is the bpp and 60 is the refresh rate in Hertz. In general, these default settings should suffice for most people.
No Sound After Installation
Two files need to be modified. Open a terminal session and launch your preferred editor:
- From /etc/modprobe.d/blacklist.local.conf remove the following lines:
blacklist snd-aoa-codec-tas blacklist snd-aoa-fabric-layout blacklist snd-aoa-i2sbus blacklist snd-aoa-soundbus blacklist snd-aoa
- Then add the following line to /etc/modules
After a reboot sound will work and alsamixer will run.
