Public bug reported:
Hello,
I've tried to use vga_switcheroo as I've got an acer Timeline. It uses an ati
card and an intel chipset.
In order to have vga_switcheroo working, I've modified my rc.local file like
this :
sleep 10
chown jean-demange /sys/kernel/debug/vgaswitcheroo/switch || true
sleep 20
echo OFF > /sys/kernel/debug/vgaswitcheroo/switch || true
sleep 10
echo "eteignation de la carte" >> /var/log/rc.local_log
touch /var/log/rc.local_execute_avec_succes || true
exit 0
But sometimes (after a unpluging or plugin my computer, using sleep) the
graphical session does not start correctly : the screen gets black and does not
switch on again. I can access to a console with ctrl+alt+F1. I've put the
dmesg.log produced when the computer does not start well.
In the console, when I try to reach /sys/kernel/debug/vgaswitcheroo/switch,
nothing happen (eg : $sudo su then $cat /sys/kernel/debug/vgaswitcheroo/switch
does nothing (the tty hang : it is not possible to do anything else)). But when
the system correctly, with this command, I can see the state of both graphics
cards.
Thanks.
