Ubuntu 10.10 gnome-power-manager shutsdown bug

Actually I don’t know in which version this bug has started, but “gnome-power-manager” just indicates that my laptop battery is charging even though I unplug the AC power supply.

Since I upgraded to the new version, the problem is even worst, since now when I unplug the AC power supply  a message pops up saying that I have less than 1% battery power and Ubuntu just shuts down.

Actually if you have this same problem, you can go to “gconf-editor” and where it says “/apps/gnome-power-manager/actions/critical_battery”, set it to “nothing”

Upgrade to kernel-2.6.27-11-generic on LG-500

Today I’ve upgraded my kernel to 2.6.27-11-generic, and some fixes were necessary to get my Ubuntu to work again.

I tried to open VirtualBox but I get this error:

VirtualBox error
VirtualBox error

Executing the command that they suggest worked like a sharm:

sudo /etc/init.d/vboxdrv setup

The other problem was due to wireless. Again I needed to recompile the madwifi so I could get it to work for the new kernel. I’ve Followed the post Re: Atheros Communications Inc. AR242x 802.11abg Wireless PCI Express Adapter (rev 01) and it’s working again! :)

VirtualBox 2.1.2 in Ubuntu 8.10

VirtualBox is an application that allows you to have several virtual machines inside your operative system.

Unfortunately the VirtualBox version 2.1.2 still isn’t on Ubuntu repository, but if you go to Download VirtualBox for Linux Hosts there you find a version that will run on Ubuntu!

Installing and running is really straight forward, but I had a problem when I tried to start a virtual machine:

VirtualBox can’t operate in VMX root mode. Please disable the KVM kernel extension, recompile your kernel and reboot (VERR_VMX_IN_VMX_ROOT_MODE).

To fix this I’ve just followed the indications in VirtualBox can’t operate in VMX root mode.

Here is VirtualBox 2.1.2 running Windows XP inside Ubuntu in Seamless mode

Ubuntu 8.10 (Intrepid Ibex) in LG E500-SP23P laptop

I’ve done a fresh install of Ubuntu 8.10 (intrepid ibex) in my LG E500-SP23P laptop and I’ll document my troubles and my thoughts about the new Ubuntu version.
I’ve switched to Ubuntu since it’s 5.10 version and in this laptop since its 7.04. My previous version was 7.10 and some of the problems that I had in installing it then, I saw them in this new version too…
This laptop has the following specs:
Processor

  • Code Name: Meron
  • Processor: Intel Core 2 Duo Processor T7500
  • FSB: 800Mhz
  • Speed: 2.2Ghz
  • Cache: 4Mb L2 Cache
Graphic Card
  • NVIDIA® GeForce® 8400M 128Mb VRAM -TurboCache até 384/896Mb
Wireless Card
  • Atheros AR5007EG Wireless (802.11b/g)
Sound Card
  • Audio card Intel Corporation 82801G (ICH7 Family) High Definition
After installing it I’ve noticed that wireless didn’t work. In 7.10 it also didn’t work, so I expected that it should be fixed by now. After some googling I’ve find out how to solve this.
Another problem that I’ve faced was that I couldn’t activate Desktop Effects. I’ve went to System/Apperance and in the “Visual Effects” tab activated “Extra”. Here ubuntu showed me the option to activate the proprietary driver, and I choosed “Enable”.
Activate proprietary driver
Activate proprietary driver
So I choose to “Enable” and another error showed up:
Enable to enable driver
Enable to enable driver
Another problem that I had (I also had in 7.10 version and never could fix it) is that if I plugin headphones, I continue to ear sound from the front speakers.
I haven’t fix this yet, when (if) I do, I’ll let you know ;)
