[Work] [Leadership] Fwd: Pomoc pri rjesavanju problema sa HP racunalom na Linuxu

Wed Aug 8 11:35:30 CEST 2012

nisu jedini s tim problemom.....

možda nisam na tragu problema možda jesam, ali korištenje vlasničkih
drivera na Ubuntu distribuciji je meni stvorilo probleme slične njihovima i
maknula sam ih/deinstalirala...  jednostavno koristiti ono što ima Ubuntu
out of the box.... najnoviji Ubuntu radi super na malim ekranima ali nije
baš dobar s velikim rezolucijama (imam osjećaj da je složen samo za netbook
računala).... jer meni na 22' monitoru/desktop računalu starom cca 8 godina
nije nikako radilo a na netbooku starom godinu dana nemam problema...

Neka probaju s Xfce ili Lxde sučeljem i neka ne prtljaju po vlasničkim
driverima i neka puste da to distribucija detektira sama

molim iskusnije da se jave....

> *Kratki opis problema:*
> Problem se javlja pri visokim rezolucijama (1600x900) sa grafickom
> karticom. Pojavljuju se treptece horizontalne crte preko cijelog ekrana kao
> da nije pogodjena frekvencija osvjezavanja. Problem je isti na razlicitim
> ditribucijama (pokusali smo sa zadnjim Debianom i Ubuntuom). Takodjer i
> nekoliko drivera (intel, i915,..) daju iste rezultate. Jedino VESA radi
> dobro, medjutim nema visoke rezolucije. Takodjer smo pokusali i
> konfigurirati Xorg server, medjutim sa forsiranjem nekog odredjenog moda,
> GDM se uopce ne pokrece nego izbacuje gresku "Cannot open display". Najveci
> progres smo dobili sa konzolom i *uvesafb* driverom, pri cemu je
> rezolucija dobra (1600x900) i nema flickera, medjutim cim se pokrene
> graficko sucelje, rezolucija se opet vrati na 800x600.
