Go back to previous kernel?
 

I recently upgraded my kernel on my laptop, i dont remember what it was but it was on a Debian system. Anyway i did some things and now when i try to use my built in wireless card my system locks up (see thread http://www.linuxquestions.org/questi...client-595336/).
My question is would it be possible to remove the new kernel and start over?

You shouldn't have to remove the new kernel. Just edit your /boot/grub/menu.lst to boot the older kernel, which is probably still located in /boot.

Copy down your old kernel version.

Change the current (new) kernel listed in the GRUB entry for your Deb installation to the older kernel that you just copied down. Save, exit all, reboot.

Luck!

Yeah i can boot to the older one, but i need to use the newer one (i cant get vmware to work on the old one). So i just want to remove it and start over.

Ah... sorry, Keith. I misunderstood you. :(

Sure, just remove it with Synaptic (graphic front end for Apt).

Thanks for your help, it worked, well removing it anyway :)

Maybe you need to update (reinstall current version) VMWare on the newer kernel to get it to work??? I'm not familiar with VMWare, so can't help you much there. I just find it odd that a kernel upgrade would cause you problems setting up an app that previously worked on the older kernel.

Actually it's the opposite. I cant get vmware to work on the older kernel, but it works on the newer kernel. My current problem is that my wireless does not work on the newer kernel (and now on the older one). I think i'm going to reinstall Debian, dont really want to but cant think of anything else to do.

I don't think a reinstall in necessary, Keith. If you can't get some other opinions/assistance here at LQ, c'mon over to Scot's Newsletter Forums --> All Things Linux and post your issue over there. Bruno or others will walk you through a diagnosis and resolution, if one is possible. Don't get me wrong LQ is an OUTSTANDING forum, but sometimes you just can't get the step by step assistance here like you can at smaller forums. Tell 'em Eric sent you over at ATL. :)

Luck!

I hate to say this, but i already reinstalled debian, wireless is working on new kernel and old one, now just need to set up vmware.

I will still checkout that forum, it could come in handy sometime.

Good for you! Glad you got it working. A reinstall is the "sledgehammer" method of fixing Linux. However, sledgehammers are useful tools at times. ;)

Maybe see you at Scots!

Later...
