Nvidia G 105M problemi

[igadmile]

Pozdrav

Imam laptop Acer Extensa 5635G s gore navedenom karticom, koja ocekivano lose radi s open driverima.
Nakson sto instaliram propertary drivere, ekran mi se podijeli na "6 kopija desktopa" rezolucije 640*480 koji se svi ponasaju kao jedan.

Na netu sam nasao rjesenje ovog problema, a to je da napravim ovakav xorg.conf:

To rijesi problem s rezolucijom, koja je sad ok, 1366*768, ali pojavljuju se jos neki prblemi:

1. na naslovnoj strani ovog portala, gornji dio :

"treperi" ko na starim CRT-ovima sa refresh rateom od 60 hz. isto je sa svim slicnim sivo-bijelo-crnim kombinacijama.

2. zahtjevnije 3d igrice poput World of Padman (loada se, ali ne pokrene), ili Tremolous (pokrene se, ali se srusi pri promjeni rezolucije odmah nakon pokretanja) ne rade.

Inace dektop efekti rade bez problema.

Ono sto bi vas molio je da pogledate gore navedeni xorg.conf i kazete mi jel sve dobro podeseno.

Driver je instaliran preko openSUSE-ovog repository-a, verzija je 190.42. No iste probleme sam imao i na ubuntu 9.10

Kod mene dobro radi s 185.18.36 driverom.

izgleda da je problem u BIOS-u laptopa.

evo sta je Nvidiin programer odgovorio na problem s "6 desktopa":

If you're referring to the problem that adding the NoTotalSizeCheck mode validation override works around, then it's a bug in the laptop -- the flat panel has an invalid EDID and the driver is rejecting the nonsensical modes that it contains. You should contact your laptop vendor to see if there's an updated BIOS for it.

Ajd malo vidi ovaj link:

možda nađeš štogod korisno za nvidiju. Pogledaj i odgovore na dnu, ima i tamo sitnih i korisnih trikova.

Evo da javim pozitivne pomake u vezi s ovom karticom.

Problem sa "6 malih ekrana rezolucije 640*480" je rijesen sa zadnjim beta driverom: 195.36.03 (inace, problem je bio u tome što je EDID u laptopu, koji nosi informacije o monitoru, bio potrgan, ili nije postojao. Dakle problem u BIOSU laptopa)

Problem sa "trzanjem" ekrana na sivo-bijelim kombinacijama može se riješiti dodavanjaem ovog parametra u xorg.conf pod sekciju Screen (na ovom linku je objasnjeno u cemu je u biti problem: http://www.nvnews.net/vbulletin/showthread.php?t=148273)

Moram pohvaliti Nvidia ekipu s Nvidia Linux foruma, stvarno brzo odgovaraju, i brzi su u popravljanju bugova.
