Hello, I tryed successfully the switcheeroo patch v13 by switching to radeon in console before starting X, I didn't try another way on Envy 13 (1050ef). This patch is for testing purpose currently, imo only advanced linux user should try it.
Patch can be dowloaded here : http://people.freedesktop.org/~airlied/vgaswitcheroo/0001-vga_switcheroo-initial-implementation-v13.patch I used the vanilla kernel 2.6.33.2 and patch it with switcheeroo v13 on gentoo with a recent Xorg radeon driver currently 6.13.0 in gentoo denomination. In my case I made i915 and radeon driver as module with modeset disable by default. Then I made a little init.d script that load those modules with modeset enable, then switch to radeon card. The durty little script look like folowing and do any check, use it without waranty : modprobe i915 modeset=1 sleep 1 modprobe radeon modeset=1 sleep 1 if [ ! -e /sys/kernel/debug/vgaswitcheroo/switch ]; then mount -t debugfs none /sys/kernel/debug fi echo DDIS > /sys/kernel/debug/vgaswitcheroo/switch sleep 1 I don't know if the load order have impact but for my linux that order work. Note that error in script or mistake on loading this modules can leave you with a blank screen, and some time freeze the computeur. Since I use this script I have not a lot of trouble. The first bug I noticed is that in radeon as output the britghness of the screen cannot be changed. The second issue is, when I closse the screen and I open it back, the computer seems to freeze. I hope this help, if I have time I will produce a step by step tutorial :) Best regards. _______________________________________________ Mailing list: https://launchpad.net/~hp-envy Post to : [email protected] Unsubscribe : https://launchpad.net/~hp-envy More help : https://help.launchpad.net/ListHelp
