From: Wakko Warner on 3 Jul 2010 18:20 I have a Dell Inspiron 5100 with an ATI Radeon Mobility M7 (7500 R100 PCI ID 1002:4c57 sub 1028:0149). Immediately when radeon.ko is loaded, the screen goes blank (The backlight stays on). I have fbcon compiled into the kernel (I also tried as module). I am unable to get the screen to work again until I reboot. The logs did not appear to have any errors after the module loaded. The system was still responsive on the network. I tried kernels 2.6.33 and 2.6.34. I can provide kernel output if needed. -- Lab tests show that use of micro$oft causes cancer in lab animals -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo(a)vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/

Also 2.6.34 (with modeset=0) doesn't do 3D very well on this system. Some objects look ok, some are garbled, some do not appear at all. The gears from xscreensaver does not show up at all. -- Microsoft has beaten Volkswagen's world record.

From: Marvin on 5 Jul 2010 13:30 Hi Wakko, as nobody seems to have answered yet, I think it's better that you file a bug against the radeon driver (bugs.freedesktop.org, one bug for each defect). There may be similar bugs already, so please check this also.

Doesn't appear to be. I mentioned above that I have no errors. I forgot about it saying something about the BIOS. It shows this [drm:radeon_get_bios] *ERROR* Unable to locate a BIOS ROM > then a few days ago hit another: > https://bugzilla.kernel.org/show_bug.cgi?id=16335 > (keep in mind still uncertain on a fix for this, reverting the commit > gets me up and running(I created a patch, but an umsure if it's a right > solution)). This one appears to be X related. In my case, this happens immediately at radeon.ko load (with modeset=1). Verification of this was booting with init=/bin/sh and modprobe radeon. Instant black screen. The backlight stays on. > if none of these are what your hitting, then maybe(if you can) do a > bisect on this! I tried 2.6.32.15. I noticed that KMS was in staging. This one didn't do a black screen. I saw mostly white, green and a pinkish color. All were kind of washed out and were in vertical lines. KMS on this laptop has not worked with stock kernels. I booted Ubuntu 10.04 live CD and it appears that KMS was working. I don't know what patches they have in the kernel for this or what is different. -- Microsoft has beaten Volkswagen's world record.
