Re: [Bug 773471] Re: No brightness on LCD monitor (Acer Aspire 5732Z)
I just used the manager to update to 2.6.38-9-generic #43+kamal~mjgbacklight4-Ubuntu and the brightness works much better. The login panel remains dark. Once in your session, the amount of backligth evolves contrary to what the popup display indicates and i've experienced sudden changes of brightness. But all this is quite easy to deal with and future upgrades will do the fix for sure. Thanks a lot for the feedback, guys!

Re: [Bug 773471] Re: No brightness on LCD monitor (Acer Aspire 5732Z)
Hi again, same thing with Natty. It's like the PPA doesn't get installed. I am probably missing something: $ sudo add-apt-repository ppa:kamalmostafa/linux-kamal-mjgbacklight $ sudo apt-get update Is that it? I guess not! (Thanks for the setpci command, it makes Natty functional for me through a simple-to-blind-type shell containing it.)

That's it, on 10.10 I can see well but there's no reaction to hotkeys (snapshots attached). Going to try blind typing on 11.04, install Kamal's kernel and let you know.

Re: [Bug 773471] Re: No brightness on LCD monitor (Acer Aspire 5732Z)
Hi again, things are back to normal on 10.10 after a new reboot. Kamal's PPA is still here but brightness won't vary with the Fn commands. I'll try to install it on Natty as soon as I fetch a flashlight and let you know what happens.

Hi all, sorry for the news, but I just tried Kamal's PPA on 10.10 and after reboot I got a totally black screen as a result (gulp!). I'm in the failsafeX mode from the recovery mode right now. Hope to find a way to undo the PPA. Maybe I should've tried directly on 11.04? I'll try doing so despite the results on 10.10. The question is how, as one can't see a thing. I've read somewhere that a flashlight may help see what's going on in your screen (!). I'll let you know. In the mean time any suggestions are welcome!

Re: [Bug 773471] Re: No brightness on LCD monitor (Acer Aspire 5732Z)
Can you confirm (e.g. with uname -a on a terminal) that you really booted into the patched kernel 2.6.38-9.43+kamal~mjgbacklight4. If you did not select the kernel at boot time (hold shift to get a grub menu to select) you might have booted into the 2.6.39 kernel from the previous test. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/773471 Title: No brightness on LCD monitor (Acer Aspire 5732Z) -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
