i855GM a dualhead (trochu delsi)

[Vaclav Stepan]

Dobre odpoledne,

zkousim rozbehat na Thinkpad R50e dualhead konfiguraci
a zle se mi nedari. Prosim nepovedlo se Vam to nekomu
se stejnym HW nebo aspon s necim kde je i855GM grafika?

Totiz - je tam Intel 855GM chip, ktery pod Windows
a podle dokumentace (man i810) i pod X ma zvladnout
jak clone-display, tak dual-head (mam zatim dojem,
ze z toho proste vypadnou dve Screen, takze pujde
normalne pouzit Xinerama).

Po ruznych experimentech jsem dospel k zaveru, ze
nasledujici konfigurace (X.Org 6.8.2) by mela byt
funkcni. No neni a vysledek je, ze X nenabehnou
a obdari mne hlaskami:

...
(WW) I810(0): Bad V_BIOS checksum
...
(II) I810(0): VESA BIOS not detected
(EE) I810(0): VBE initialization failed.
...

Nastesti to po poweroff bylo v poradku, ale trochu
mne to vydesilo :-)

Vidite prosim v nasledujici konfiguraci problem?
Je potreba neco udelat nejak jinak? (Jak?)

Moc dekuju
