Dotaz: Akcelerace i915 na Ubuntu studio(pardon, delší)

[HonzaRez]

Zdravím, zkouším Ubuntu studio 7.04 na notýsku Asus M6A, grafika i915. Problém je v tom, že mi COSI odmítá vzít mnou upravený xorg.conf a stále mi ho "politicky korektně" mění.

>>>>>>>>>>>>>>>>>>>>>>>>>>>

Section "Device"

Option "RenderAccel" "1"

Identifier "Card0"

busid "PCI:0:2:0"

Driver "i810"

VideoRam 65536

VendorName "All"

BoardName "All"

Option "XAANoOffscreenPixmaps" "true"

Option "XaaNoPixmapCache"

Option "DRI" "true"

EndSection

Tohle všechno jsem vygooglil, že by tam mělo patřit. Jenže po restartu tam mám tohle:

Section "Device"

identifier "Card0"

busid "PCI:0:2:0"

A akcelerace není, glxgears dokážou cca 700fps, direct rendering:no.

V logu nic není, jen v xorg.0.log je asi toto:

Nechápu, prostě se mu to nelíbí. Předtím na Mandrivě mi ten konfigurák myslím přesně takhle urychloval. V sekci modules mám všechno, co by tam mělo být, už od instalace...

Díky za radu.

Odpovědi

[regnarg]

To musí být změněno nějakou Ubuntu službou, která nesouvisí s X, protože tohle chování není normální. Jsou dvě možnosti, buď zjistit, která služba to způsobuje, a neutralizovat ji (ale to nevím, v ubuntu se nevyznám), nebo těm změnám zamezit. Několikrát se mi osvědčil následující postup obrany různých konfiguráků proti změnám: spustit chattr +i /etc/X11/xorg.conf pod rootem. Je to hnusný trik, ale většinou funguje. Od té doby nebude možné soubor nijak změnit až do spuštění chattr -i /etc/X11/xorg.conf v případě nutnosti změn.

[pakanek]

To je opravdu dirty hack. Nejaky proces se stale ten soubor bude snazit upravit - ac neuspesne.

[David Jaša]

700 FPS v glxgears je dost na to, aby akcelerace jela. Jak je na tom ppracer, cuká se nebo jede plynule?

[pakanek]

Zalohuj si ten soucasny a vygeneruj si novy pomoci xorgconfig. Ten potom zkus upravit. Zkus vypatrat treba pomoci lsof co pristupuje k tomu konfiguraku.

Jinak se mi dosti osvedcila volba

Options "DDC" "false"

co se tyce rychlosti glxgears. Ackoli od X.org 7.0 jde rychlost jaksi dolu.

btw. akcelerace funguje myslim jen pri barevne hloubce 16-bit, pokud jde o ovladace i810
