Package: general Severity: normal Hello, I'm currently running the latest version of Debian Testing (as of 4/11/2013 02:00 GMT+2), and I've noticed a problem while changing the backlight of my screen. When I press the "Lower Brightness" key combination (FN+Home on my Lenovo SL500) and keep it pressed, the backlight keeps pulsing on the lowest setting, like it's trying to go one step lower but it can't. This keeps happening as long as the key-combo is pressed. I've noticed that the stepping for the brightness level is kind of unstable as there's also a small pulse-like effect going on when I change brightness in general. It gradually becomes more evident as I get close to the lowest brightness setting. The amount of steps is inconsistent, as it requires 14 steps to go from brightest to lowest and only 5 to go from lowest to brightest. Also, the OSD freezes when keeping the key combination pressed, instead of gradually changing to the highest or lowest setting. After a while (a few seconds), it unfreezes and shows the correct value. It also appears that you can't do anything while the OSD is frozen. The same problem also occurs when using Ubuntu 13.10 (tried that about a week ago... so many crashes), on the same laptop. This problem did not occur in Wheezy or Ubuntu 13.04. I'm not really sure but I think that this problem has appeared in Testing today, after installing the latest updates: [UPGRADE] gnome-icon-theme:amd64 3.8.3-1 -> 3.10.0-1 [UPGRADE] gnome-icon-theme-extras:amd64 3.6.2-2 -> 3.6.2-3 [UPGRADE] gnome-icon-theme-symbolic:amd64 3.8.2.2-2 -> 3.10.1-1 [UPGRADE] gnome-terminal:amd64 3.8.4-1 -> 3.10.1-1 [UPGRADE] gnome-terminal-data:amd64 3.8.4-1 -> 3.10.1-1 [UPGRADE] libtxc-dxtn-s2tc0:amd64 0~git20121227-1 -> 0~git20121227-2 [UPGRADE] libtxc-dxtn-s2tc0:i386 0~git20121227-1 -> 0~git20121227-2 [UPGRADE] libxml-libxml-perl:amd64 2.0010+dfsg-1+b1 -> 2.0106+dfsg-1 [UPGRADE] python-apt:amd64 0.8.9.1+b1 -> 0.9.1 [UPGRADE] python-apt-common:amd64 0.8.9.1 -> 0.9.1 [UPGRADE] python3-apt:amd64 0.8.9.1+b1 -> 0.9.1 I also installed (and configured) the lm_sensors and hddtemp packages. I'm using gnome-shell. I don't know whether a gnome-shell extension is causing this. I've disabled any newly installed extensions but it hasn't done anything.

It is probably maybe a bug in the kernel, have you tried newer versions? (I'm closing this bug as it's not helpful to add it to the huge pile of kernel bugs just guessing...) cheers, HolgerAttachment: signature.asc
