Thread: Experimental Nvidia working in recovery mode but not after normal boot

hi there,

have strange problem. tried make compiz work using experimental 3d support of free nvidia driver, because suffering bug in proprietary driver (click here launchpad entry). free driver mean 1 shows "experimental 3d support nvidia cards" in "additional drivers" manager (note: reason, option present when no proprietary driver active).

strange thing is: driver not provide 3d support, , behaves awful (lots of glitches , on) when boot system normally. when instead boot grub menu recovery mode, select "failsafe graphics", , select "restart x", whole thing works perfectly! running experimental 3d driver, have compositing working, 3d animations on docky. somehow, failsafe boot sequence right normal boot sequence not. when reboot in normal mode, screwed again.

have no idea statistics system should include here, because have no idea possibly wrong. running 32bits natty in classic mode, on ahtlon dual core 4850e machine, geforce 6150 le graphics card.

these normal , recovery entries in grub.cfg:

code:

menuentry 'ubuntu, linux 2.6.38-8-generic-pae' --class ubuntu --class gnu-linux --class gnu --class os {     recordfail     set gfxpayload=$linux_gfx_mode     insmod part_msdos     insmod ext2     set root='(/dev/sda,msdos1)'     search --no-floppy --fs-uuid --set=root 74a69553-666f-4ca6-afbb-27d59b4793ac     linux    /boot/vmlinuz-2.6.38-8-generic-pae root=uuid=74a69553-666f-4ca6-afbb-27d59b4793ac ro   quiet splash nomodeset vt.handoff=7     initrd    /boot/initrd.img-2.6.38-8-generic-pae } menuentry 'ubuntu, linux 2.6.38-8-generic-pae (recovery mode)' --class ubuntu --class gnu-linux --class gnu --class os {     recordfail     set gfxpayload=$linux_gfx_mode     insmod part_msdos     insmod ext2     set root='(/dev/sda,msdos1)'     search --no-floppy --fs-uuid --set=root 74a69553-666f-4ca6-afbb-27d59b4793ac     echo    'loading linux 2.6.38-8-generic-pae ...'     linux    /boot/vmlinuz-2.6.38-8-generic-pae root=uuid=74a69553-666f-4ca6-afbb-27d59b4793ac ro single      echo    'loading initial ramdisk ...'     initrd    /boot/initrd.img-2.6.38-8-generic-pae }

any suggestions welcome!

the experimental support package libgl1-mesa-dri-experimental complements open-source nouveau driver, say. can, in fact, install proprietary nvidia driver enabled using synaptic or apt-get. don't know why doesn't present in jockey (additional drivers) when nvidia driver enabled. might bug.

whatever - wonder if nvidia driver has not been purged system, , somehow sequence you've found via recovery mode gets around this. 3 things check:

1 - have in /etc/modprobe.d/nvidia-graphics-drivers.conf. make sure nouveau driver not blacklisted. in system current nvidia driver enabled, file symlink /etc/alternatives/nvidia_modconf, if it's not there in system, don't worry it.

2 - check see if have /etc/x11/xorg.conf file. need 1 nvidia driver, not nouveau. having said that, xorg.conf in system terse, doubt interfere nouveau driver.

3 - open synaptic , search packages beginning nvidia. package nvidia-common ok have, presence of others may interfere nouveau driver.
