[Kernel-packages] [Bug 1007765] Re: brightness adjusting crashes system
Dear George, I am quite sure, this does not fix the problem. I investigated this in deep now, let me elaborate on this. At first I forgot to mention, my system is entirely a 64bit one, may be this is importand. Secondly, I have only one AMD/ATI HD4500 card build into my notebook as a graphincs card. This is no intel, radeon or fglrx issue. But may be forcing intel interface reveals some stuff intel fixed in their code path. I got fluctuate_bl.sh to test this out from here: https://bugzilla.kernel.org/show_bug.cgi?id=57571 This script penetrates the /sys/class/backlight/acpi_backlight0/brightness interface with a interval which may be configured. It can be called penetrating another interface. My Kernel offers acpi_backlight0 (values 0..15) and radeon_bl0 (values 0..255). When I penetrate the acpi_backlight0 the system freezes almost immediately, penetrating radeon_bl0 lasts a bit longer to make the system freeze. What I learned is, adding a delay for example of 0.2s looks more stable on first sight but acpi interface lasts not much longer either, pentrating radeon_bl0 lasts going out to smoke a cigarette but will crash. Again, rdaeon_bl0 looks a bit more robust. The delay seems to be relevant for a statistic feeling. Changing with xorg.conf or kernel command line from acpi interface away to vendor one could look better but only on first sight! If I do echo 0 >/proc/sys/kernel/nmi_watchdog Both tests are running for ages (0 delay!). SOLVED! I tested the acpi_backlight=vendor kernel command line. acpi_backlight0 vanishes and dell backlight appears under /sys/class/backlight. Despite of the fact there is no brightness interface under this new directory I can penetrate the interface with the fluctuate_bl.sh script, but only the backlight OSD appeears (running kde here) but the brightness does not change. Penetrating the still existing radeon_bl0 interface yields to the well known crash.

[Kernel-packages] [Bug 1007765] Re: brightness adjusting crashes system
Hello to you all! I am showing up here because I have the same issue. I found this thread this morning after blaming the hardware on my notebook for a year but rethinking this to be a software issue this morning. I will try out the solutions here to contribute on this this evening. Please, how are the actual informations on pinning down this issue to a subsystem? What I want to contribute at first is technical stuff. I have exactly the same issue on this constellation (all tried out in 2013): Dell Studio 1558 with BIOS A04 and A12, HD4500 ATI debian or archlinux installed several installed linux-3.1n.x versions several recent fglrx catalyst legacy drivers several recent open source radeon drivers Yes, no ubuntu launchpad issue at all! Yes, all the same crash but the pattern on screen after crash is different: fglrx is flashing a couple of chars in the pattern, radeon displays a mor simple pattern with no flashing chars.
