"RC Kernel"

[captcadaver]

According to this article, some "RC kernel" exists that can make Ubuntu Netbook Remix run like awesome on my EEE 900:

How do I, uh... get this kernel?

[coffeecat]

The link to get the kernel is there in step 8! :p

Download the *apw5_i386.deb files for linux-image* and linux-headers*. That's two files. You can use the 'sudo dpkg -i *deb' terminal command if you want or simply double-click on the .deb files and let the graphical app gDebi install them for you.

By the way, this kernel does not make NBR "run like awesome". There is a bug in the regular kernel that makes mouseover on the NBR desktop very sluggish and awkward. This apw5 kernel simply fixes this bug.

:(

I spend money on a degree, yet I can't read...

Thanks much for your help, kind sir.

Ahh, I recently updated my system with everything the update manager suggested. It replaced my kernel and I'm back to lagginess.

I tried to do reinstall the RC kernel again. Despite having this kernel, I'm getting that icon lag again...

Thoughts?

I haven't used my Eee for some time, so I'm guessing what's going on here.

The special kernel is version 2.6.28-11, but the latest official kernel is 2.6.28-13 and that is what you're probably now booting into. Obviously, they still haven't fixed this issue. However, the 2.6.28-11 kernel should still be installed and should still be available from the grub menu.

If your grub menu is hidden, press esc shortly after you start up (you should see a prompt top left of screen) to reveal it. Then select the -11 kernel from the menu.

If you want the system to boot into the special -11 kernel as the default or have the grub menu show up at start up, you'll need to edit your /boot/grub/menu.lst file. Post back if you need any help with this.

Edit: just to confirm (or refute) my assumptions, please open a terminal and post the output of:


uname -r

That'll tell us which kernel you've booted into. While you're about it, post the contents of /boot/grub/menu.lst as well.

I never knew that was the GRUB menu did... cool. I went in and selected the correct KERNEL, and it runs nicely:

2.6.28-11-generic

So, what do I edit in this file?

change the red number to a 3.

[coffeecat]

change the red number to a 3.

Errr.. not quite! :wink: Don't forget that grub counts from 0, so to boot from the third menu entry as default, that line needs to be "default 2". If the OP sets it to 3, the system will boot into recovery mode as a default - which will be unfortunate. :|

captcadaver, you've got two options, both of which involve editing menu.lst, for which you need root privileges. To do this, open a terminal and...


gksudo gedit /boot/grub/menu.lstEither, change the default line to...


default 2or move the whole of the two -11 stanzas to above the -13 ones. What that means is that this lot:

By the way - all those lines beginning with a hash (#) are commented lines. They are skipped when the system parses them. So, if you want the menu to appear when you boot up, simply put a # in front of the line "hiddenmenu".

I love you.

good catch coffeecat, I knew that but must have went braindead. I have 0 for my default...go figure!
