Dotaz: Dual head rozliseni

[stynak]

Dobrý den, zprovoznil jsem pod Ubuntu 6.10 Dual head, mám ale problém s nastavením rozlišení u druhého LCD. Používám 19" LCD (nativně 1280x1024) a 15" LCD (nativně 1024x768). Problém je v tom, že při výběru rozlišení se mi u sekundárního monitoru nenaskýtá možnost změny rozlišení na jiné, než 800x600 i přesto, že v xorg.conf žádné takovéto rozlišení není. Lze nějak měnit rozlišení "natvrdo" pomocí konzole ve smyslu "--screen 1 set resolution 1024x768" a pod...? Zde je můj xorg.conf soubor. Děkuji za jakékoliv rady. # /etc/X11/xorg.conf (xorg X Window System server configuration file)

[Martin]

Podle mne není možné mít různé rozlišení pro oba monitory, pokud mají být obrazovky vedle sebe (viz option RightOf).

Zkus v xorg.conf změnit rozlišení 19" monitoru na 1024x768.

[stynak]

No tak právě já různá rozlišení mám, jak již jsem psal (1280x1024 a 800x600, které chci na 1024). Další věc je, že nemám klasický big Desktop, ale vypadá to jako 2 sessions (na každém monitoru mám vlastní plochu, lištu a nelze přesouvat mezi nimi okna).

[petr_p]

A samostatne dostanete z mensiho monitoru 1024x768? Ja jsem to taky jednou zkousel, ale to jsem mel dve graficke karty a nastavit rozliseni samozrejme slo.

[Luboš Doležel (Doli)]

Stejnou věc provozuju doma, bez problémů.

Zkuste nanečisto spustit Xka příkazem X -logverbose 7. Potom se podívejte do /var/log/Xorg.0.log, kde by nvidia ovladač měl velmi podrobně zdůvodnit, jaká rozlišení povoluje, jaká ne, a proč zvolil to, které zvolil

[stynak]

Tak jsem provedl tento příkaz a zde je úryvek z logu. (II) NVIDIA(1): Assigned Display Device: CRT-1
(WW) NVIDIA(1): No valid modes for "1024x768"; removing.
(WW) NVIDIA(1):
(WW) NVIDIA(1): Unable to validate any modes; falling back to the default mode
(WW) NVIDIA(1): "nvidia-auto-select".
(WW) NVIDIA(1):
(II) NVIDIA(1): Validated modes:
(II) NVIDIA(1): "nvidia-auto-select"
(II) NVIDIA(1): Virtual screen size determined to be 800 x 600

to 1280x1024, 800x600 mam kvuli HOMAM3, aby slo fullscreen, jiank to nepouzivam. Jinak 1. monitor je CRT, druhy LCD

aha, ja mam ale jen jednu plochu, tak to je jiny pripad...

[milda]

hele, celkem jsem se na tom vydrbal minulý týden. Připojoval jsem k nvidii quadro nvs 3 monitory a ve finále to bylo úplně na pohodu. Ujisti se, že máš ten správný ovladač pro svoji kartu. Po instalaci ovladače je tam softik, který se jmenuje tuším nvidia-settings nebo tak nějak, a tam to naklikáš. Jestli chceš klonované obrazovky, nezávislé plochy, xineramu, kterej monitor je kterej atd. ...
