[Kernel-packages] [Bug 1315834] Re: 1002:983d [Acer Aspire V5-122P] Unable to adjust screen brightness using Radeon driver
Confirmed - upgrading to the latest bios (2.12) fixes both the brightness issue and fixes the suspend and resume problem present in later kernels.

[Kernel-packages] [Bug 1315834] Re: 1002:983d [Acer Aspire V5-122P] Unable to adjust screen brightness using Radeon driver
I have been asked to test a kernel patch for this bug but I am struggling to do so. I am able to obtain the source to the most recent Ubuntu kernel and compile it. The patch, however, appears to have been written for a later kernel version. The 3.13 kernel will not compile after applying it. I believe I need at least 3.14, maybe 3.15. I am aware of the mainline kernel repository that contains kernels pre- built upstream kernels for ubuntu. No source is provided. I need a way to either: 1) get hold of the source for these mainline packages in the same way I can get the source for the most recent ubuntu kernel; or 2) figure out how to compile the pure kernel source from kernel.org for Ubuntu. Can anyone advise before I go back to the kernel devs? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1315834 Title: 1002:983d [Acer Aspire V5-122P] Unable to adjust screen brightness using Radeon driver Status in “linux” package in Ubuntu: Triaged Bug description: While using the Radeon driver, I am unable to adjust the screen brightness on my Acer Aspire V5-122P.

Will I am indeed using the Radeon driver, however, for clarity, you are not looking inside the acpi_video0 directory for the other entries but rather its parent directory. Also it might not be called radeon_bl0 on your system. Essentially if you list your /sys/class/backlight directory you will (probably) have multiple entries (one of which is acpi_video0). For example, I have two: acpi_video0 and radeon_bl0. You may have different entries, especially if you are using the fglrx driver. You need to go into each of these entries/directories one by one and try to adjust the brightness as described in my original post. Hopefully one of them will work. From my (very limited) understanding, I think that this is the essence of the bug (i.e. the acpi_video0 interface device is not properly hooked up to the actual display adapter). Having said that, what do I know?!

[Kernel-packages] [Bug 1315834] Re: 1002:983d [Acer Aspire V5-122P] Unable to adjust screen brightness
No fix yet as such, however, thanks to kernel developer AAron Lu I can confirm that there is a workaround to manually adjust screen brightness. Its not overly practical, but you possibly write a script to do it. The sequence of commands is below. Essentially it involves accessing your video card via /sys and poking the brightness value directly. Mine video is detected as radeon_bl0. I will revert when I have further information. lewis@HappyFunMeaowMeaow:~$ sudo -s [sudo] password for lewis: root@HappyFunMeaowMeaow:~# cd /sys/class/backlight/radeon_bl0 root@HappyFunMeaowMeaow:/sys/class/backlight/radeon_bl0# cat max_brightness 255 #Max value for your hardware root@HappyFunMeaowMeaow:/sys/class/backlight/radeon_bl0# echo 200 brightness #Example root@HappyFunMeaowMeaow:/sys/class/backlight/radeon_bl0# echo 10 brightness #Example root@HappyFunMeaowMeaow:/sys/class/backlight/radeon_bl0# echo 255 brightness #Example root@HappyFunMeaowMeaow:/sys/class/backlight/radeon_bl0# -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1315834 Title: 1002:983d [Acer Aspire V5-122P] Unable to adjust screen brightness Status in “linux” package in Ubuntu: Triaged Bug description: I am unable to adjust the screen brightness on my Acer Aspire V5-122P.

Chris I have prepared my email with the information requested as advised in the link you provided (see attached). I have determined that I should sent it to xorg-driver-...@lists.x.org (being listed as for discussions on ati driver related issues. under graphics issues). Before I send it, please can you confirm that this is the correct choice based on the nature of this bug? Is this a graphics issue for these purposes? In addition, I am unsure what you mean by please provide a direct URL to your e-mail to the mailing list once you have made it. I can (obviously) send an email in plain text, but I don't know of an easy way to make such sent email available via a URL (though I could possible host something myself).

Chris For completeness, I can confirm what Chris has said (i.e. the fglrx drivers do not solve the problem). My testing shows almost the same situation as Chris has kindly noted. By way of a summary: 3.15rc5 kernel with fglrx drivers - X won't start 3.13 kernel with fglrx drivers on AC power - exactly the same bug as my original report (screen alternates between full brightness and black) 3.13 kernel with fglrx drivers on battery power - almost the same problem except screen alternates between full brightness and what looks like around 5% brightness. In summary the fglrx drivers do not appear to provide a work around.

Chris I can confirm that the bug exists after having updated my bios (2.08 - 2.10). I have also checked the new bios with the upstream kernel for completeness. The problem remains identical to the description given in my initial report. I have removed the outdated bios tag and set this back to confirmed (which I hope is the correct procedure).
