Unable to change screen brightness on Zepto G14b Laptop.

[Daniel Holm]

I just got my new Zepto G14b laptop and are using an updated Karmic install. The thing is that I'm unable to change the brightness of the screen. It doesnt even change when I plug/un-plug the AC-adapter.

When I use the 'Fn'-keys for changing the brightness they seem to work as the notifiaction works for it, but noting really changes on the screen. Same thing with the brightness-applet for the Gnome-panel.

Earlier snippets from the syslog, which is included, says something about the power-management. But it could also be about the earlier problems I had with the battery power and such, which now is fixed, but I still included it just in case.

Otherwise I cant seem to find anything about it in ither dmesg or syslog. Except that it doesnt recongnize the keycodes when I press the 'Fn'-keys. But I figured, when they do work, that's not important.

Keep upp the awesome work, everyone!

Hi Daniel,

Can you take a look at https://wiki.ubuntu.com/Hotkeys/Troubleshooting and attach any additional information here? Thanks.

Sure, here it is, but still the keys works and Gnome recognize them. It looks more like the signal for actually changing the brightness doesn't work.

xev | sed -n 's/^.*state \([0-9].*\), keycode *\([0-9]\+\) *\(.*\), .*$/keycode \2 = \3, state = \1/p':
keycode 122 = (keysym 0x1008ff11, XF86AudioLowerVolume), state = 0x0
keycode 122 = (keysym 0x1008ff11, XF86AudioLowerVolume), state = 0x0
keycode 123 = (keysym 0x1008ff13, XF86AudioRaiseVolume), state = 0x0
keycode 123 = (keysym 0x1008ff13, XF86AudioRaiseVolume), state = 0x0
keycode 232 = (keysym 0x1008ff03, XF86MonBrightnessDown), state = 0x0
keycode 232 = (keysym 0x1008ff03, XF86MonBrightnessDown), state = 0x0
keycode 233 = (keysym 0x1008ff02, XF86MonBrightnessUp), state = 0x0
keycode 233 = (keysym 0x1008ff02, XF86MonBrightnessUp), state = 0x0
keycode 78 = (keysym 0xff14, Scroll_Lock), state = 0x0
keycode 78 = (keysym 0xff14, Scroll_Lock), state = 0x0
keycode 78 = (keysym 0xff14, Scroll_Lock), state = 0x0

Please help. I'm still stuck with a to bright screen.

I finnaly got is linked to the packade 'smartdimmer' which is made just for changing brightness with nvidia-cards and even certain Zepto-laptops. This is one of them.
