I have the same problem with 10.04 Beta on the N150. A workaround is to create a file called brightness.sh somewhere with this content:
#!/bin/sh sudo setpci -s 00:02.0 F4.B=$1 Then just execute: chmod a+x brightness.sh After that you can execute brightness.sh with a hex number between 0 (off) and ff (full brightness) like this: ./brightness.sh 50 This is kind of ugly but it is much better than not being able to change brightness at all. I'm not an expert on kernel and X dirvers but for me the problem seems to be that the X driver doesn't support the xrandr brightness property. If I call xrandr --verbose on the N150 this property doesn't appear while it is present if I execute the same command on a machine where changing the brightness with the gnome panel applet works. ** Attachment added: "Output from xrandr --verbose on N150 with Ubuntu 10.04 Beta" http://launchpadlibrarian.net/43806197/xrandr.out ** Changed in: ubuntu Status: New => Confirmed -- Cant adjust the screen brightness on Samsung N150 with netbook remix. https://bugs.launchpad.net/bugs/546005 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
