View Full Version : [ubuntu] Wow, Ubuntu has messed up my comp: graphics, battery, wireless, etc.

November 8th, 2008, 11:26 PM
I recently got a new computer (HP dv5 notebook PC, Atheros AR242x ethernet card, AMD Turion X2 64 bit 2.1 GHz processor, 4 GB of memory). I started out with Vista 64 which was working fine.

Anyway, I finally installed Intrepid 8.10 using Unetbootin, but now I have quite a few problems that I can't seem to fix.

1) Battery problems. It says my computer's battery capacity is at 69% (poor). And whenever I go onto battery power, the batter icon doesn't seem to update (stuck at 100%). Plus, I keep hearing this high-pitched buzzing which I'm pretty sure is coming from the battery, and it is especially bad when I am running on battery power. Also, I'm pretty sure the battery life is significantly shorter than when I was running Vista.

2) The wireless card is incompatible and I can't seem to get it working. I've enable the wireless card, but their are no wireless networks available. In addition, the touchpoint wireless button on my laptop is stuck on orange (off), and I can't seem to change it to blue (on). I've tried using Mad Wifi, but I can never seem to get through all the steps without something failing. If someone could tell me how to use (with very simple language), it would be very helpful.

3) Every time I shut down and sometimes when I open programs, the screen will very quickly flash colorful lines across the screen as the window opens. I have my graphics card enabled.

Anyway, that's it. My computer was running fine with Vista, but I wanted to use Linux to increase the speed (which also doesn't seem to be significant at all). Hopefully you guys can help me with these problems.

When you say your wireless card is incompatible what exactly do you mean? The drivers that come standard with Ubuntu rarely work. Generally you need to install drivers specific to your wireless module.

To determine what wireless module you are running use this command:

lshw -C network

As per your wireless issue, a quick Google search for "Atheros AR242x ethernet card " gave me this: http://ubuntuforums.org/showthread.php?t=850185

Because many hardware manufacturers are unwilling to release open source drivers, you can't realistically expect Ubuntu to just make everything work...

Granted, I've never had an issue with this before because I've always researched my hardware before installing Ubuntu because I wanted to make sure it will be compatible.

In order for Ubuntu to utilize all 4 gigs of RAM, you'll need to run the 64bit edition (Vista as well... no 32bit OS supports 4 gigs of RAM).

Also, you used UNetBootin to install... it's not an officially supported package and you should have used WUBI if you're inexperienced with installing.

I don't want to discourage you or start a flame war, but your lack of planning is what messed up your computer, not Ubuntu.

The first time I installed Ubuntu on my last laptop, I just bought a magazine with a disk and installed from there. Should I just re-install using that disk?

Also, I installed the 64 bit version and unetbootin was the only thing that worked.

What version is on that disk? I think your best bet would be to download Ubuntu 64bit, defrag Windows and run the WUBI installer from within Windows (it's in the ISO, you'll need something like UltraISO in windows to open it)

Just be sure to regularly defrag Windows, as WUBI will put the new installation of Ubuntu within the free space of your Windows install.

Hope this helps ;)

Please write "lspci" in terminal and post the output.

Use the madwifi drivers for your atheros card, they worked for me. I know 8.04 had issues where when you updated the kernel headers you had to do a "make clean" and "make install" again, but I believe ubuntu 8.10 solved that. My advice is to get ubuntu 8.10 from www.ubuntu.com and then install the madwifi drivers.

There are multiple threads about that wifi card since 8.10's release. I got mine going with ndiswrapper and apparently if you open the backports, drivers are available there - I haven't tried that, as ndiswrapper is working fine. I could not get the madwifi drivers to work.

When I first had Ubuntu installed, I encountered similar problems--the one regarding my Wireless card and my battery. Don't worry, everyone new to Ubuntu encounters those problems, and almost all the questions have already been answered in the forums.

For the battery however, I thought that my battery life was shorter in Ubuntu rather than in Windows but in the end, it's my fault for not getting the modules designed to get my battery working. Although it's easier to recondition batteries in Windows (since ThinkPad has a utility..), it seems the battery's capacity gauge in Ubuntu (the one that pops up the first time you boot Ubuntu) is quite accurate.

So just like the answer to the wireless card problem, I suggest entering keywords concerning your battery in the search bar. ^_^
