Comment 2 for bug 680897

tim, thank you for reporting this and helping make Ubuntu better. Regarding your title:
kernel 2.6.32-26-generic didn't recognise netcard and display get worse

Please do not stack multiple issues into one report. Hence, this report will only focus on the netcard not being recognized. If you need a fix for a display problem execute the following at the Terminal and feel free to subscribe me to it:
ubuntu-bug linux

As well, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you run the following command in the development release from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux <replace-with-bug-number>

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.
