Dotaz: posunuty obraz v X/framebufferu

[Pavel Löbl]

Zdravim, tak jsem se konecne dostal k tomu slavnymu archu.

Kdyz nabootuju do konzole obraz je v poradku. Jak pustim Xka obraz je mirne rozmazany a posunuty asi o 20px doprava. Pote co v X zmacknu auto-conf na monitoru obraz se spravi, ale po navratu do konzole je obraz posunuty o ten puvodni kousek doleva a zpet uz ho nic nedostane. Pouzivam monitor ACER AL1916(VGA).

[dustin]

Ani ruční posunutí obrazu ovládacími tlačítky monitoru?

[Pavel Löbl]

Tak to samozrejmne lze, ale radsi bych abych to nemusel pri kazdym prepnuti do/z konzole posouvat rucne. Tim nic sem mel na mysli auto-conf a reset.

[jirka22]

Tohle jsem "vyřešil" tím, že jsem nastavil jinou snímkovou frekvenci pro X. Monitor si potom pro každý režim pamatuje nastavení. Jestli je na LCD 60, 70 nebo 75 Hz je normálnímu člověku jedno.

[Pavel Löbl]

Uz to frci. Do Xorgu sem pridal modeline a v grubu to orezal na minimum. Tak snad vyreseno.
