Hi, This post is gonna get the Ubuntu know-alls bamboozled, I'm sure. I have had recurrent sound problems with my Dell Inspiron 1440 with Dual boot of Windows Vista and Ubuntu Jaunty.

I just upgraded my HP Compaq nc6220 from Jaunty to Karmic. Jaunty was sweet, no issues at all. Under Karmic, I have the Intel cpu hog bug plus restart just hangs the machine after dropping out of Xorg.I've seen a lot of gripes about the Intel Xorg bug but no solutions - can this be sorted or do I go back to Jaunty?

BTW long-time Linux user, Ubuntu since 6.04.

I recently purchased a lenovo G580 laptop. It does not have a separate graphics card. I also installed ubuntu and windows 7 64 bit . Lenovo provided a driver cd for windows 7. I installed all the drivers. The lenovo FN+up and down brightness control works fine in windows 7. But it does not work in Ubuntu.

[ubuntu] Wake on Lan Karmic 3 years 15 weeks ago

Hello everybody, I'm a complete newbie on this board, so thanks in advance for the time u may spend to help me deal with my small problems. So here we are: I m running karmic on a dell optiplex 330, with a broadcom network controller NetLink BCM5787, and wol doesn't want to work since upgrade to karmic.

I have done that :

I an running Karmic. Recently my keyboard has started behaving oddly. It does not respond to three arrow keys and the delete key. I also have Win7 installed on another partition. The keys work fine there.

I did,

Code: xev | grep -A2 --line-buffered '^KeyRelease' | sed -n '/keycode /s/^.*keycode \([0-9]*\).* (.*, \(.*\)).*$/\1 \2/p' And got the following results:

[ubuntu] Lenovo T61p - No sound 3 years 26 weeks ago

Hello,

I have a Lenovo T61p (wider version of the T61) and am running Karmic Koala. Everything is working great... except the sound. I had the same problem with Jaunty Jackalope.

Any ideas?

what other info do you need to treat the patient?

Thanks!

so basically when i put the ubuntu installation disc of Ubuntu 11.10 inside and run a Live session everything works fine (i can press Fn + Arrow Up and Fn + Arrow Down to control the screen Backlight).

But after that i install the system, it doesnt work anymore...

Ever since upgrading my Lenovo IdeaPad Y530 from Jaunty to Karmic, I have been plagued with severe stability issues, rendering my laptop essentially useless.

I switched on my laptop this morning (HP Compaq nc6320) as usual and tried to log in, only to find that neither trackpad nor keyboard were working! If I reboot into a recovery mode shell, the keyboard works until I move on to normal boot. If I boot from an Ubuntu install disk (run from CD), both trackpad and keyboard work. Everything seemed OK last night when I shut down.
