    Re: Ubuntu on Lenovo ThinkPad Edge

    found a solution by searching around. [https://bugs.launchpad.net/ubuntu/+s...s/+bug/554980]

    just open terminal and copy:

    xinput --set-prop --type=int --format=8 "SynPS/2 Synaptics TouchPad" "Synaptics Two-Finger Scrolling" 1 0
    xinput --set-prop --type=int --format=32 "SynPS/2 Synaptics TouchPad" "Synaptics Two-Finger Pressure" 4

    Eric,

    How did you get to update the bios? At the lenovo site there is a newer versin of bios (1.17/1.13) in .iso format, however I was not able to boot with it using a USB flash disk (tried writing it with unetbootin).

    USB stick doesn't work, I used an external DVD/RW drive instead.

    Re: Ubuntu on Lenovo ThinkPad Edge

    Some observations about performance. For the last three weeks, I've been running an in-house kernel compiled to include the dsdt file provided in http://forum.notebookreview.com/leno...essions-6.html. My bios/ecp version was 1.12/1.04.

    Before compiling with the provided dsdt file, I got an error after login, about not being able to use CPU frequency scaling. The dsdt included kernel got rid of that and I could see the change in CPU freq in idle times thru the panel CPU monitor.

    However, that really did not have an impact on battery life, at least not as much as I thought it would. After I upgraded my BIOS/ECP firmware yesterday to version 1.18/1.09, I switched back to kernel without dsdt file override (hpoing that the 1.18 upgrade may have implemented a fix in the dsdt table). But nope, its still not fixed as I still get the CPU freq scaling error.

    The interesting thing is there is virtually no difference in power rating between kernels with or without a dsdt override. The power consumption remains in the same level, around 21W.

    Additionally, when I used a kernel with a dsdt override the backlight adjustment keys on the top row of the keyboard did not respond. Actually the level indicator appeared on the screen and the level changed as the key was pressed, however the actual brightness level did not change.

    Another thing is when I close the lid and the machine goes to suspend, it wakes back up, but is totally unresponsive and requires a forced reboot by pressing the power button. This problem occured regardless of the type of kernels used (with or without the dsdt override), however it is fixed with the bios upgrade (to ver 1.18).

    Overall, the battery drains fast as it feels, it takes less than two hours, at a rate of approx 21 W.

    However, using the proprietary ATI catalyst driver reduces power rate to a band 12-14 W, representing a reduction of around 30% in comparison with the ubuntu's own ATI drivers.

    Re: Ubuntu on Lenovo ThinkPad Edge

    Just got Ubuntu 10.04 running on my Edge 14 and I'm really enjoying it If you have time, can you guys submit your findings to the ThinkWiki? Here's an article I wrote.

    Has anyone gotten hdaps working?

    Re: Ubuntu on Lenovo ThinkPad Edge

    i have recently installed lucid on a thinkpad edge 13 " (intel core2duo)..
    almost everything i need worked out of the box..
    the most annoying problem: RESUME AFTER SUSPEND

    the screen turns black, the red light (i) indicates sleep mode, but the fan continues to run and the machine is stuck and i need to switch it off.

    does anybody have the same problem or knows a fix? i have read in this thread that resume after suspend works..

    and another question: how to enable 2-finger-scrolling in a persistent way? restarting disables it.

    thanks a lot!
