Misadventures of the Compaq CQ50Z and Ubuntu 8.04


This is a compilation of my previous posts regarding this on other forums.

I've been scratching my head for a few days, now.


So far this has been a wild ride. Hours so far of searching various forums, scavenging google, and reinstalling a few times have brought me here. I still have a ways to go, too, but at least I've made a little progress.

My two main concerns for right now are as follows:
Atheros AR5009 wlan NIC
nVidia GeForce 8200m

To begin with, I installed the AMD64 version. Installed and booted fine, but wlan would not work at all. The physical wireless button up top was stuck on orange and would not budge to blue. Also, the disabled nvidia device driver, when enabled, fails to download. I did a little research and gave up early because I know 64bit still sucks.

So I reverted back to x86. Wlan still was a lost cause on install, but the nvidia restricted driver actually downloaded and installed. Rebooted the computer aaaaand black screen. Seems the driver didn't take. I'm still pretty new to linux and haven't used it for a few years, so my fix for that was a clean reinstall.

I scavenged my search options. I found the solution to my video driver issues, though not completely. At least now I have my full 1280x800 resolution display. Link:
http://www.albertomilone.com/nvidia_scripts1.html

The only issue I'm having with that involves display artifacts when the framerate gets too high. For example, scrolling down a webpage quickly. A minor annoyance with general computer use, but open up a game and it would be a nightmare I'd imagine.


As for wlan? Well, I tried a couple things. First, what didn't work. Then, as of right now, what only works halfway.
This didn't work:
http://ubuntuforums.org/showthread.php?t=865971

Following those instructions did nothing for me, despite everyone's success. However, I'm not surprised as not all devices behave alike. With the install of the madwifi drivers, nothing happened. My NIC still wasn't being picked up by the network manager.

Second method I found involved the mac atheros drivers compiled into a debian package. Link:
http://ubuntuforums.org/showpost.php...62&postcount=3

This method got ubuntu to realize my wlan NIC exists. The button is blue up top as if everything is honkey dory. Just one problem, though. It can't pick up any wireless networks, it's borked. I tried through the GUI and through "sudo iwlist scan." Nada. When I try to connect to my wireless network manually with the correct settings, it just hangs.

One last thing, too. I haven't investigated much into it yet, but, the sound is scratchy and intolerable.
My chipset is nForce, not sure which revision.

That's where I am, now. If anyone has had any similar issues or experiences, or if anyone has found some solutions, please share them here. I would definitely appreciate it.


Second post:

I was able to find out more specific chipset information.

nForce MCP77MV is the northbridge. There really isn't a lot of information about this chipset, yet.


I hear there's troubles with nForce chipsets in general. Any ideas?



And third:

I just gave ndiswrapper an honest shot, using the original driver from HP for my wireless card.
Source:
http://h10025.www1.hp.com/ewfrf/wc/s...747533&lang=en
It's further down the page;
Atheros Wireless LAN Driver 06-2008 2.00 B » Version: 20.64M

I extracted the package w/ cabextract:
Code:
athrext.cat   athrx.sys  data2.cab    netathr.inf   setup.exe  setup.iss
athrextx.cat  data1.cab  ISSetup.dll  netathrx.inf  setup.ini  SP39403.cva
athr.sys      data1.hdr  layout.bin   _Setup.dll    setup.inx
I got these two files for use:
netathr.inf
athr.sys


ndiswrapper gladly took these and convincingly said, "Okay, sir! You're good to go!"

...

Restart the system, no go. Next I try:

sudo gedit /etc/modules
added "ndiswrapper" on its own line.

I assume this is somewhat similar to Run in the registry or somesuch.

Restarted the system, nada.

sudo modprobe ndiswrapper doesn't show or tell me anything.


"ndiswrapper -l" returns:
Code:
netathr : driver installed
	device (168C:002A) present
Yet iwconfig only returns lo and eth0.


sudo ndiswrapper -m:
Code:
module configuration already contains alias directive

module configuration already contains alias directive

module configuration already contains alias directive

module configuration already contains alias directive

module configuration already contains alias directive

module configuration already contains alias directive

module configuration already contains alias directive

module configuration already contains alias directive

Sorry, there's a lot of information, here. But I'm still lost, haha. I'm always willing to try, though. Thanks for any help.

I can make your life easier - this laptop does not play well with linux. The things you are talking about are known not to work. As of this date - there are no out-of-the-box fixes.

You should be able to run the graphix with the vesa driver - or use envy. If you want it to look cool - you should experiment with the low-spec 2D desktops... wow your freinds with that snappy-zappy feel

The wireless card is all right - it's the controller that is giving you problems. Later releases may support the controller. They don't right now. You'll have to use a dongle.

If you are serious about fixing these issues - get yourself some source code and the compiler packages.

I have some experience with programming, how dirty can it get? I am willing to do some trial and error. Maybe a push in the right direction?

Would I have to modify the source? And I have never touched a driver before, so this could be interesting.

Well, for one thing, did you try installing the Linux drivers from the nVidia website. I'm running on a desktop, but they're working spledidly for me. I'm even running the AMD64 package. I haven't bothered with the nForce chipset drivers. Those worked fine out of the box.

As for the wireless, when you ran ndiswrapper, did you use lsmod to make sure ndiswrapper was running? You shouldn't need to restart the computer. In fact, unless you successfully added the module to the startup list, it can confuse things.

What did ifconfig tell you? Were you able to bring up the interface?

Ouch! I have a CQ50Z too!

I first tried a wipe-clean, then install of XP instead of the Vista that came on the system, and found that they do not have many of the drivers written for XP to run on that hardware. Crap! Then I loaded Fedora 9-64 and that booted up just fine. But like you, no WiFi, sound is scratchy, and video sucks. Now I'm working on finding Linux drivers? I will post anything useful, and check back it you find anything.

The main issue is proprietary drivers - so the source code is a trade secret. You can try writing to the HW manufacturers explaining your situation...

For nvidia - try using envy to install a driver or just use the nv or vesa driver with 2D. Keep watching the nvidia forums.

The aetheros card has free software drivers...

Have you tried installing 32 bit linux?
