Hi, I have a Gigabyte GV-R455D3-512I which is essentially a Radeon HD 4550 graphics card. It's not quite operating properly, particularly when connected to two monitors. However, I have a probably-not-very-common setup and this might be causing the issue somehow, and it may not necessarily be a bug in the radeonhd driver. So, I'm not sure, and hopefully you can point me in the right direction to investigate further. Hardware setup: Dell 640m laptop with an Intel 945GM integrated graphics card ATI Radeon HD4550 connected via an Expresscard-to-PCIe 1x adapter The hardware seems to be working properly, and the radeonhd driver mostly works with a single monitor. Software setup: Ubuntu Hardy Heron - linux 2.6.24 ish - xserver-xorg 1:7.3+10ubuntu10.2 - xserver-xorg-core 2:1.4.1~git20080131-ubuntu9.2 with xserver-xorg-video-ati 1:6.12.1-0ubuntu1~hardy from https://launchpad.net/~tormodvolden/+archive/ppa XOrg.0.log also says: (II) RADEONHD(1): Unknown card detected: 0x9540:0x1458:0x21AE. If - and only if - your card does not work or does not work optimally please contact radeonhd@opensuse.org to help rectify this. Use the subject: 0x9540:0x1458:0x21AE: <name of board> and *please* describe the problems you are seeing in your message. so you probably should at least update your hardware ID numbers. When I have a single monitor attached to the Radeon, I can change the screen resolution with command line xrandr. When I have two monitors attached to the HD 4550, and I log into Gnome/X, my mouse cursor stays within Screen 0 (the Intel graphics) and I can't move over to focus onto Screen 1 (the Radeon). If I have one monitor attached, and I log into Gnome/X, I can move my mouse between Screen 0 and Screen 1 (so I can do stuff on Screen 1) However, if I then attach the second monitor to the Radeon, I cannot set the second monitor to a non-Off resolution from command line xrandr. (Throughout this, there is no external monitor attached to the Intel 945GM, only the laptop's internal LVDS). Is it possible I need an up-to-date xserver-org-core? Or perhaps the HD 4550 isn't well supported by radeonhd at the moment? I can also provide logs and re-do my testing if required, but I didn't want to jump the gun yet. Thanks for any help you can provide. Beng Tan -- To unsubscribe, e-mail: radeonhd+unsubscribe@opensuse.org For additional commands, e-mail: radeonhd+help@opensuse.org
