I have the same situation as Carlos: 11.2 automatically installed kernel-default and not the *-desktop. It was a "clean" install (on brand new HDs).
Apart from the "Why did the installer do this?", how do I change to the *-desktop kernel? Uninstall the default and at the same time select desktop (and let nature take its course)?
Or install both and choose at boot time... but we need to know what advantages/disadvantages we get, in order to choose correctly.
The way I read the reference which Dean provided, the opening statement pretty well summarises what the desktop kernel is about: QUOTE It seems to me that the current default kernels are somewhat hurting openSUSE's performance perception. Current kernel configs are OK but are not very well suited for desktop usage. In the future I would like to see a kernel package that is optimized for desktop usage. Current timer settings and no preemption really (sometimes drastically) hurts openGL performance and applications such as wine and causes alot of issues such as audio studdering. It would be nice to see a separate desktop performance kernel package with options such as Preemption model set to Preemptable Kenel (low-latency Desktop) and Timer Frequency Set to 1000 Hz, HPET support, Tickless System, disable optimize for size, disable Control Group support and disable Group CPU scheduler. You could also disable items and modules that are extremely rare in a desktop environment such as ATM support, Infiniband etc etc as these are not typically used in a desktop scenario which would be a large majority of openSUSE users. Further performance enhancements would also be done through out the system aimed at desktop use as well such as disabling barriers (even making it a simple checkmark option in the partitioner). Such optimizations for desktop usage can overcome openSUSE's reputation as being slower then the other mainstream distro's. The kernel settings alone can make up to a 30-40% increase in framerates in wine games for example and can cure alot of hiccups in multimedia apps. UNQUOTE After the above, from the verbal exchanges by the various Initials I could gather that the pae kernel will only be installed if there is a flag set to indicate that you have at least 4GB of RAM installed and that a server kernel will be installed if you are running a server; after that what is called a default kernel and what is called a legacy kernel becomes kinda confusing - except perhaps that the legacy kernel may be the one which is installed on i386 machines. But don't take my word about any of this! :-) BC -- The chief cause of problems is solutions. -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-factory+help@opensuse.org
