Hi cosama, I wanted to install a fresh new ubuntu and try your advices, but it appears that all is supported out-of-the-box on the very last ubuntu 14.10 ! Backlight works well :) (I just had an issue with wifi, but while checking additional drivers fixed it) Anyway, thanks for your help ! -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to fglrx-installer in Ubuntu. https://bugs.launchpad.net/bugs/1318314 Title: brightness adjustment does not work on Thinkpad E145 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/fglrx-installer/+bug/1318314/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

Hi tom, Not sure, I followed the description above, from a fresh buntu-gnome 14.04 install and it still works perfectly. Do have the radon_bl0 brightness control folder? Check by typing in a terminal: ls /sys/class/backlight/radeon_bl0 If so what happens if you type into the terminal: sudo bash -c echo 10 /sys/class/backlight/radeon_bl0/brightness Did you update your grub after setting the boot parameters?

Hi @cosama, With your method, I havea flash of the brightness to the value I set, but it quickly go back to the old value. I have Xorg drivers. Do you have an idea of what I could do ? Is there any plan to fix this issue ? It makes linux nearly unusable with this computer. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to fglrx-installer in Ubuntu. https://bugs.launchpad.net/bugs/1318314 Title: brightness adjustment does not work on Thinkpad E145 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/fglrx-installer/+bug/1318314/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
[Ubuntu-x-swat] [Bug 1318314] Re: brightness adjustment does not work on Thinkpad E145
I just got a brand new Thinkpad E145 and had the same problem after a new install of ubuntu-gnome 14.04 (BIOS 2.02). After trying out all possible combinations of kernel parameters and drivers I finally found a solution that worked for me. I had to disable the fglrx drivers and use the X org xserver driver. Then I used the kernel parameters (/etc/default/grub): GRUB_CMDLINE_LINUX_DEFAULT=quiet splash acpi_backlight=vendor video.use_native_backlight=1 quiet splash was set by standard. I tried also acpi_osi options but with these options I couldn't get it running. The backlight then appears as /sys/class/backlight/radeon_bl0/ and can be changed by setting the level in the brightness file in that folder (0-255). When I had fglrx running, I had the impression the driver over ruled the brightness setting, it always reverted back to a standard value. It is not a perfect solution, I would prefer being capable of using fglrx but for now I can live with it. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to fglrx-installer in Ubuntu. https://bugs.launchpad.net/bugs/1318314 Title: brightness adjustment does not work on Thinkpad E145 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/fglrx-installer/+bug/1318314/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

I have the same problem as well, but this is on a Thinkpad T510 (about 5 years old).

It appears this bug is fairly well known. Here's an article called Fix Brightness Control Not Working for Ubuntu 14.04 Linux Mint 17 at http://itsfoss.com/fix-brightness-ubuntu-1310/ . Unfortunately, the fix listed is only for the Intel Video card. For what its worth, the brightness control worked fine on this laptop with Ubuntu 10.04. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to fglrx-installer in Ubuntu. https://bugs.launchpad.net/bugs/1318314 Title: brightness adjustment does not work on Thinkpad E145 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/fglrx-installer/+bug/1318314/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
