| Changing kernels Within the last couple of days I upgraded memory on my laptop to 4GB, and changed from SUSe 10.3 to 11.1 (formatted the drive and clean install of 11.1)and dual boot Windoze XP Pro. The laptop is a Toshiba A105 S4547 system based on the Intel 945 chipset and a core duo Intel processor. Graphics is Intel 945DM.
I was not paying attention as closely as I should have been on the install. I ended up with the PAE kernel, and I think install in my case defaulted to that. I do wonder if it was partially due to the 4 GB of RAM in the machine --even with flashing to the latest BIOS (and the machine is spec'd for 4 GB) all thats recognized is 3 GB.....
Soooo between installing both XP Pro and 11.1 and trying to get ready for an upcoming trip...I ended up with the PAE kernel. I ve experienced various problems on the laptop with programs that work well on the desktop under the same OS....
I have since changed to the 2.6.27.23-0.1 default kernel. I installed the default kernel using YAST, booted to it, and uninstalled PAE. I still have a number of apps that seem not to work right although if anything the machine seems faster with the default kernel, video seems smoother.
Question is.... changing a kernel even using a package manager.....is there a lot of garbage left around i.e a lot of stuff not quite right? I ve been considering with what problems I ve had with a few apps, a clean install.
This is the first time I have used the PAE kernel and understand that its for extended memory support but have read in a number of places about various problems with it (particularly with NVidia graphics cards),
Time for a reinstall? or....
Thanks

| Re: Changing kernels first, the kernel is just the kernel, there is nothing else that differs, so your issues likely don't have anything do to with whichever one you have installed
second, I dunno about SUSe, but I've run PAE kernels for many years with nvidia - never had an issue.
third, yeah a non PAE kernel is faster - the tradeoff is larger memory space for *slightly* slower performance
fourth.... use a 64 bit version, maybe?
To specifically answer your question - changing or installing additional kernels (you can have a bunch installed - pick the one you want with Grub at boot) doesn't leave anything behind. Whatever issue you're having, it's not related to the kernel or having multiple kernels installed at one time or other.

Thanks very much for the information. I ve used SUSe for a number of years but have never tried different kernels...and am very ignorant about how a lot of the OS works.
Regards and Happy 4th

| Re: Changing kernels Thanks very much for the info. I did some online research on PAE. I ve never messed about much with kernels leaving that pretty much to defaults.
In using the machine since I changed back to the default, I have noticed the desktop is more responsive and it seems that boot takes less time. Additionally a couple of my apps, most notably the VOIP client, that would not run under PAE, now run fine under the default. Still have not resolved the machine not seeing the last gig of the 4....still only 3 indicated but as one can imagine its pretty quick!!!
I dont know much at all about kernels.... less than a thimble full. Thanks very much to everyone here who has responded to this. I ve got some reading to do its evident.
Happy 4th of July
