Microsoft Windows recovery seems to be on a 10GB partition /dev/sda2, backup before you start.


Do *not* try to emerge gcc-4.3 before doing stage1 install (just for -march=core2), or if you do, don't forget to run 'gcc-config 1' after unmerging gcc-4.1 else emerge will fail with "C compiler cannot create executables" (took me two hours to solve).

Also keep in mind that bootstrap uses only one job and thus takes a lot of time to finish, no matter if you have two or even more cores (-j4 in my MAKEOPTS).


After Installing newest Xorg (and solving circular dependencies by temporarily removing X useflag), startx detected all the hardware, direct rendering was working, resolution was highest possible, glxgears did 60fps (no matter if I opened one or three instances, obviously refresh rate related), KDE4.1 works great, including compositing effects

Touchpad seems to not see the number of fingers used, and thus multi-finger clicking requires EmulateTwoFingerMinZ option in xorg.conf (95 seems to be the right value for me)

Multimedia Keys

with hp_wmi module all the multimedia keys work (dmesg shows *something* when pressed), only the quicklook key (between power and "presentation" button, the one that starts the PC when off) is not recognized by hp_wmi and thus is not bindable (or is, but not as easily as the others)


Currently (as of git-sources-2.6.27-r6) sound is working only through headphones, I am working on that now <- SOLVED

"options snd-hda-intel model=laptop" in modprobe.conf and reboot solves, "modprobe snd-hda-intel model=laptop" didn't (possibly because modprobe on loaded module doesn't mean "reload")


emerge hibernate-script and enable (and emerge of course) vbetool, hibernate-ram is working great, but sometimes (happened to me three times) the laptop doesn't wake up (everything starts up but the screen remains off and the computer is frozen) and a "hard" shutdown is required (hold the power button for longer time)
