[Bug 116464] Re: Display brightness slider does not show up on Dell Latitude D810
On a Dell C610 running Hardy Alpha5 the dimmer works on AC, but not on battery. I assume that's how it's designed. On AC it indicates that it dims from 100% to 0%, but this is not quite right. The lowest setting (0%) does not blank the screen, but puts it at where the screen is on battery power. -- Display brightness slider does not show up on Dell Latitude D810 https://bugs.launchpad.net/bugs/116464 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is a bug assignee. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs

Confirmed on Thinkpad X40. Furthermore, issuing echo up /proc/acpi/ibm/brightness doesn't do anything (like it used to) -- Display brightness slider does not show up on Dell Latitude D810 https://bugs.launchpad.net/bugs/116464 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is a bug assignee. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs

I can confirm this on a ThinkPad X32. Running gutsy with all updates, uname -a prints Linux skx 2.6.22-14-generic #1 SMP Sun Oct 14 23:05:12 GMT 2007 i686 GNU/Linux. If I do # cat /proc/acpi/video/VID/LCD0/brightness I get not supported like Shadows_Friend, but # cat /proc/acpi/ibm/brightness I get level: 7 commands: up, down commands: level level (level is 0-7). Also, the gnome-power-manager Preferences dialogue doesn't display the brightness slider like it used to do. -- Display brightness slider does not show up on Dell Latitude D810 https://bugs.launchpad.net/bugs/116464 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is a bug assignee. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
[Bug 116464] Re: Display brightness slider does not show up on Dell Latitude D810
I think my problem is located in the fact that there I have no real ACPI-support for my Acer-model. The brightness control via the hotkeys seems to be done by the BIOS not by any ACPI-event. Even the available acer-acpi module doesn't support my Travelmate C200 series notebook. I hardly have access to ACPI-functions via the proc filesystem. I only get following answers if i try to access any of the ACPI-stuff: #cat ./acpi/video/VGA/LCD/brightness not supported So it can be concluded that it is an issue of ACPI-support. Maybe the other people affected can confirm this? -- Display brightness slider does not show up on Dell Latitude D810 https://bugs.launchpad.net/bugs/116464 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is a bug assignee. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs

[Bug 116464] Re: Display brightness slider does not show up on Dell Latitude D810
I have exactly the same issue on my Acer Travelmate C202TMi. I can control the brightness via the hotkeys. But neither the slider in the gnome-power-manager (In fact the slider is not there) nor the brightness applet work. I'm running on the latest Gutsy with all available updates. -- Display brightness slider does not show up on Dell Latitude D810 https://bugs.launchpad.net/bugs/116464 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is a bug assignee. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
