Instead of starting X like
xinit /usr/bin/icewm
and therefore loading the NVidia CUDA environment, one can simply add
[ -c /dev/nvidia0 ] || mknod -m 666 /dev/nvidia0 c 195 0
[ -c /dev/nvidiactl ] || mknod -m 666 /dev/nvidiactl c 195 255
[more_WP_Tag]to /etc/init.d/boinc-client assuming one has a single graphic card. See "NVidia CUDA Getting Started Guide for Linux", which is part of the CUDA Toolkit. The test statement is to cope for set -e in init-scripts.
If one has errors like
... kernel: [ 174.536638] NVRM: Your system is not currently configured to drive a VGA console
... kernel: [ 174.536640] NVRM: on the primary VGA device. The NVIDIA Linux graphics driver
... kernel: [ 174.536643] NVRM: requires the use of a text-mode VGA console. Use of other console
... kernel: [ 174.536645] NVRM: drivers including, but not limited to, vesafb, may result in
... kernel: [ 174.536647] NVRM: corruption and stability problems, and is not supported.
then add video=vesa:off vga=normal in GRUB, i.e.,
menuentry 'Ubuntu, with Linux 3.2.0-40-generic' --class ubuntu --class gnu-linux --class gnu --class os {
recordfail
gfxmode $linux_gfx_mode
insmod gzio
insmod part_msdos
insmod ext2
set root='(hd0,msdos1)'
search --no-floppy --fs-uuid --set=root 242bfd68-bd16-4c6a-91e4-d37362d9eabb
linux /vmlinuz-3.2.0-40-generic root=UUID=d471cc6b-d964-4841-9640-178e20720f1a ro <strong><span style="color:#2233ff;">video=vesa:off vga=normal</span></strong>
initrd /initrd.img-3.2.0-40-generic
}
To make this change permanent in GRUB one has to change file /etc/default/grub and change
GRUB_CMDLINE_LINUX_DEFAULT="video=vesa:off vga=normal"
