Hello, I'm writing this mail as I'm experiencing some issues with my ATI video card when running under Debian GNU/Linux. Problem I'm experiencing is lack of rotation, that is xrandr returns: #v+ $ xrandr --version xrandr program version 1.3.2 Server reports RandR version 1.3 $ xrandr -o right X Error of failed request: BadMatch (invalid parameter attributes) Major opcode of failed request: 148 (RANDR) Minor opcode of failed request: 2 (RRSetScreenConfig) Serial number of failed request: 14 Current serial number in output stream: 14 $ xrandr -o left X Error of failed request: BadMatch (invalid parameter attributes) Major opcode of failed request: 148 (RANDR) Minor opcode of failed request: 2 (RRSetScreenConfig) Serial number of failed request: 14 Current serial number in output stream: 14 #v- "-o normal" works but disables my second monitor. The following are my installed xorg packages: #v+ xserver-xorg 1:7.5+3 the X.Org X server xserver-xorg-core 2:1.7.5-1 Xorg X server - core server xserver-xorg-dev 2:1.7.5-1 Xorg X server - development files xserver-xorg-input-evdev 1:2.3.2-3 X.Org X server -- evdev input driver xserver-xorg-video-fbdev 1:0.4.1-1 X.Org X server -- fbdev display driver xserver-xorg-video-r128 6.8.1-2 X.Org X server -- ATI r128 display driver xserver-xorg-video-radeon 1:6.12.4-2 X.Org X server -- ATI Radeon display driver xserver-xorg-video-radeonhd 1.3.0-2 X.Org X server -- AMD/ATI r5xx, r6xx display xserver-xorg-video-v4l 1:0.2.0-4 X.Org X server -- Video 4 Linux display driver xserver-xorg-video-vesa 1:2.3.0-1 X.Org X server -- VESA display driver #v- It seems that the packages should be recent enough. Attached is output of lspci -vvv as well as Xorg.0.og and xorg.conf. The Xorg log says that "Card not in database: 0x954F:0x174B:0xE990" so I'm contacting you as advised by the message. -- Best regards, _ _ .o. | Liege of Serenely Enlightened Majesty of o' \,=./ `o ..o | Computer Science, Michał "mina86" Nazarewicz (o o) ooo +---[mina86@mina86.com]---[mina86@jabber.org]---ooO--(_)--Ooo--
