Hey everyone, I’ve been using openSUSE 12.2 64-bit KDE for the past two weeks or so on my Dell Studio 1558 laptop, and I’ve been having this weird problem with the display.
Basically, if I use the keyboard button to dim the display, but am not careful about how many times I push the button, this happens: http://paste.opensuse.org/view/raw/82124166
After this happens, I have to restart the computer by holding in the power button.
Usually, I can reproduce this, but not always. Anyone have any idea what is going on here or how to fix it?
On a side note, this was one of the reasons I initially left Ubuntu 11.x, because this thing happened quite frequently. With openSUSE, I’ve accidentally triggered it just twice.
This may be in the wrong forum category, but I am not sure what exactly is the problem or where to put it.
It would be useful if you could tell us what graphics hardware this laptop uses. From a quick search it looks like these come with ‘integrated graphics or optional 512 MB ATI discrete graphics’.
Unless you are familiar with grub, you may need to tell us whether you’re using grub or grub2. The method of adding the kernel boot parameter differs. I can’t promise that it will work for you either, but worth a go.
This did not work. I still had to power off the hard way.
Also, adding “acpi_backlight=vendor” did nothing. Except perhaps change the color the screen pixelated to. Any other suggestions?
