Resume from Suspend freezes/dedicated graphics deactivated
Posted: Thu Mar 07, 2013 6:08 am
Hey guys,
I'm still relativly new to Linux Mint and I'm looking now for a solution for quite some time for this problem.
In a nutshell: My resume from Suspend does not work anymore and freezes the System after the first Image is shown after I deactivated manually my dedicated radeon.
Now the more complex explanation:
I'm running Linux Mint 14 with Cinnamon 1.6 on a Lenovo Thinkpad Edge E320 with core i5 and have a switchable graphics solution with Intel HD 3000 and an AMD Radeon HD 6630M.These use the preinstalled driver.
Everything runs monstly out of the box and very stable, but the power consumption seemed very high with a battery life of 2-3 hours max.
I found then out that both the radeon and the intel graphics where powered at the same time and any command I found for switching or turning off specially the radeon didn't work because of not having the permission to do that even with sudo. I later read that copying the command below to /etc/rc.local still works on startup.
Checking with
shows afterwards that my dedicated is not powered anymore. That's as expected and wished
but
After I add the echo OFF-command to the rc.local I cannot resume from Suspend after closing and opening the lid as well as using:
The laptop itself seems to resume to the point of showing me the Desktop with panel, or in case of opening the lid again showing me the lock screen after that the system freezes completly!
I am not able to change to other tty screens, cannot use ctrl+alt+backspace to restart the x-server or any other keyboard input. Neither the touchpad nor the trackpoint work and the only thing left to do i to make a hardware reset and pressing the Power Button to turn it off by force. Booting/rebooting normal works even with the command just fine.
Deleting/commenting the echo command out of rc.local seems to make the suspend work again, but then I'm back to the problem of having both graphics being powered.
Up to now it seems for me that, Cinnamon/x-server have a problem with having the dedicated turned off after the initial configuration, so I have narrowed it down to the deactivated card.
Anybody an idea how to maybe find out what failes exactly and/or what could be looked up/changed? My knowledge of x-server configs is quite equally to zero...
Thanks in advance
