Bug Description
Ubuntu 9.04 upgrade from 8.10. (AMD 64 bit version). Upgrade install went ok. Newest kernel (2.6.28.11?) caused problems with video. No sound, and choppy smeary video. Installed fglrx driver for ATI 4870 (which worked perfectly in 8.10). Still had problems with video and sound, but could use graphics effects. Tried to reboot in lower number kernel. Graphics broken. Can't boot. Tried ALL kernel versions, used all recovery modes, tried to fix XOrg from recovery mode menu. Just got lockup. Went into command line with networking and used:
apt-get remove --purge xorg-driver-fglrx to remove fglrx. Can now boot into system, but graphics still not quite right.
Absolutely cannot use fglrx (unlike in 8.10) in any kernel version. It immediately breaks the system. fglrx, Compiz, full 3 D Video and sound work fine in 8.10 with fglrx driver. Now, in 9.04 kernel: 2.6.27.9 can only use Normal graphics setting; video and sound okay;(
affects: | ubuntu → linux (Ubuntu) |
Fixed:
1. Chose recovery mode and went into command line with networking. type:
apt-get remove --purge xorg-driver-fglrx to remove fglrx
this allowed system to boot into older kernel
2. In Synaptic package manager chose Metapackages, and reinstalled linux-image-generic 2.6.28.11.15
3. boot into kernel 2.6.28.11
4. Fixed Sound problem: Audigy 2 soundcard; Analog/Digital Output Jack. The function was reversed in an update.
To check. double click on the speaker icon in top panel and look for a 'switches' tab. If it's there then open and uncheck the 'Analog/Digital Output Jack'. If not there then click on 'preferences', scroll down and enable the Analog/Digital Output Jack switch, then go back and uncheck. Sound works fine now.
5. Went into system - administration - hardware drivers and installed fglrx. This time it worked fine. No problems
May have been caused by kernel being corrupted during upgrade.
If this were Windblows, I would have had to format C: and start all over from zero. Instead, I could fix it with the help of the Ubuntu community. Thanks to all the various forums that lead to this solution.
