Bok! Ima li tko u Zagrebu da malo pogleda o cemu se radi i pomogne ljudima. Bar kakav hint mailom. Ja sam pokusao, ali nista nasao nesto pametno, a mobilni pristup netu na obali nije bas neki. Ako to rijese opremili bi tim modelom svoje ucionice, vidi zadnje retke. Pozdrav, Milan ---------- Forwarded message ---------- From: "HSIN" <hsin(a)hsin.hr> Date: Aug 2, 2012 12:08 PM Subject: Pomoc pri rjesavanju problema sa HP racunalom na Linuxu To: <milan(a)linux.hr> ** Postovani g. Rajacic, sukladno telefonskom razgovoru, dostavljamo Vam opis problema i hardverske specifikacije doticnog racunala. *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. *Hardware info:* Radi se o HP All-in-One racunalu sljedecih specifikacija: product: HP Pro 3420 AiO PC vendor: Hewlett-Packard Motherboard: Quanta / 2AC5 BIOS: AMI version: LEO_707 (11/17/2011) CPU: Intel(R) Pentium(R) CPU G630 @ 2.70GHz Chipset: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Display: description: VGA compatible controller product: 2nd Generation Core Processor Family Integrated Graphics Controller vendor: Intel Corporation Subsystem: Hewlett-Packard Company Device 2ac5 physical id: 2 bus info: pci@0000:00:02.0 version: 09 width: 64 bits clock: 33MHz capabilities: msi pm vga_controller bus_master cap_list configuration: latency=0 resources: memory:fe000000-fe3fffff memory:c0000000-cfffffff ioport:f000(size=64) Ovo prijavljuje "dmesg" prilikom inicijalizacije: [ 4.336583] pci 0000:00:02.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16 [ 4.336587] pci 0000:00:02.0: setting latency timer to 64 [ 4.365978] mtrr: type mismatch for c0000000,10000000 old: write-back new: write-combining [ 4.365980] [drm] MTRR allocation failed.

Molimo vas da se raspitate medju kolegama o mogucnosti rjesavanja ovog problema, jer nam racunalo po ostalim performansama odgovara za sastavljanje buduce ucionice za pripreme i natjecanja informatickih olimpijaca.
