Zdravim,

mam v notebooku kartu Ati x700 mobility

# lspci
03:00.0 VGA compatible controller: ATI Technologies Inc Radeon Mobility X700 (PCIE)

Kupodivu som ju z closed-source drivermi zda sa rozbehal pomerne hladko (ovela hladsie ako integrovanu grafiku Intel 915M, kde bezim na vesa driver a aj tak to vselijak blbne), vsetko funguje

bez fullscreen anti-aliasing

2D akceleracia funguje, mplayer zerie asi 1% CPU pri prehravani fullscreen, X server asi 1,7%. 3D tiez, quake3 beha normalne, timedemo1 ma cca 95 fps. Funguje aj prepinanie powerstatu na grafickej karte (prepinanie taktu GPU/GM z 350/300 na 105/120 Mhz)

Chodi aj uspavanie. Suspend to RAM aj Suspend to Disk.

Otazka 1: Je este nieco, co ma vyznam rozbehat? Mam totiz moznost tuto kartu vymenit za mobilnu Nvidiu 6600, ktora ma ale asi iba 70% vykonu Ati.

Otazka 2: Je rozbehanie vsetkych uvedenych veci dokaz, ze s touto kartou asi nebudu problemy ani v buducnosti, alebo mam ist pre istotu do slabsej nvidie (moje doterajsie zivotne skusenosti sa priklanaju na stranu nvidie, pokial ide o grafiky v linuxe)? Proste som "prilis" uspesny s rozchodenim Ati karty, tak sa bojim toho, ze vezmem papierovo bezproblemovejsiu Nvidiu a ta ako na potvoru nebude fungovat ani tak ako Ati (predsa je to len notebook a teda ovela vacsia sanca na problemy).

Otazka 3: vo vystupe programu glxinfo sa objavuje Mesa, znamena to, ze nieco z OpenGL beha softwareovo?

$ grep -i mesa
OpenGL vendor string: Mesa project: www.mesa3d.org
OpenGL renderer string: Mesa GLX Indirect
OpenGL version string: 1.2 (1.5 Mesa 6.4.1)
