Nothing obvious in dmesg when I tried manually shutting down. The listing showed the system shutting down, and then starting up. No warnings, let alone errors. -- Walter Dnes waltd...@waltdnes.org
[gentoo-user] Machine reboots immediately when suspended-to-disk
I've enabled suspend-to-disk in the kernel. When I issue the command
echo disk /sys/power/state, it suspends but *IMMEDIATELY* reboots
and comes back up again. The session restores properly from the swap
drive, so at least that part works. What can I do to keep it sleeping
until I power up again?
The major non-standard items with my system are that
1) I've set the short button-press on the power-button as a panic escape
to kick me to VT1, rather than reboot.
2) I've disabled {CTRL-ALT-DEL}, because I've hit it once too often at
home after becoming used to it on Windows at work... gr
A relatively minor nuisance is due to the fact I combine vga=6 in
/etc/lilo.conf with CONSOLEFONT=lat1-10 in /etc/conf.d/consolefont.
vga=6 defaults to 8-pixel-high font on 640 pixels across by 480 pixels
high. This gives 60 rows of text, but is unreadable. Switching over to
a 10-pixel-high font gives a nicer, more readable, 48-row display.
After coming back from its very short suspend, the machine comes back
up with a 640 pixel x 480 scanline display as per vga=6. It also
remembers that I have 48 lines on my text consoles. But it gives the
full 60 row display, with the bottom dozen rows not being used. I can
straighten this out by manually issuing the command...
setfont /usr/share/consolefonts/lat1-10. Is there a script file that
can be set up to execute only after a resume?
