From: Vahis on 14 Mar 2010 04:57 I made a new installation of 11.2. I chose the pattern LAMP server among others. I didn't pay attention to the kernel version and 2.6.31.12-0.1-desktop x86_64 got installed. I took a look at this and in the description it says: This kernel is optimized for the desktop. It is configured for lower latency and has many of the features that aren't usually used on desktop machines disabled. What disabled features do they mean here?

It appears that nobody else has an answer to your question. Kind of curious to know the differences myself, now that you brought it up. I'm also on the desktop kernel, and don't recall having an option to select which kernel I wanted on install. With 11.1 it was the pae kernel.

But I ran into something else, maybe nothing to do with kernel version. I've installed and run vmware server 1.x.x successfully through several versions of openSUSE. Using my own notes on my site to install. I decided to try virtualbox. I ran into a wall trying to get USB I decided to go on with vmwareserver. I couldn't compile the modules anymore. I tried the 2.x and 1.x versions both, no cigar. I installed the player and it runs fine, with usb support. I may try those with the default kernel later. Or I may not, I only need the virtual XPee for one thing, Nokia PCSuite, so I'm pretty cool with just the player.

If you have the kernel sources installed, diff is your friend :-) And because I can be kind, here's a quick look at the .config differences between kernel-desktop and kernel-default. You'll want to have a non-proportional font to view this properly: desktop/.config default/.config =======================================|======================================= CONFIG_LOCALVERSION="-0.3-desktop" CONFIG_LOCALVERSION="-0.3-default" # CONFIG_GROUP_SCHED is not set CONFIG_GROUP_SCHED=y CONFIG_FAIR_GROUP_SCHED=y CONFIG_RT_GROUP_SCHED=y # CONFIG_USER_SCHED is not set CONFIG_CGROUP_SCHED=y # CONFIG_CGROUPS is not set CONFIG_CGROUPS=y # CONFIG_CGROUP_DEBUG is not set CONFIG_CGROUP_NS=y CONFIG_CGROUP_FREEZER=y CONFIG_CGROUP_DEVICE=y CONFIG_CPUSETS=y CONFIG_PROC_PID_CPUSET=y CONFIG_CGROUP_CPUACCT=y CONFIG_RESOURCE_COUNTERS=y CONFIG_CGROUP_MEM_RES_CTLR=y # CONFIG_CGROUP_MEM_RES_CTLR_SWAP is not set CONFIG_MM_OWNER=y # CONFIG_PREEMPT_NONE is not set CONFIG_PREEMPT_NONE=y CONFIG_PREEMPT=y # CONFIG_PREEMPT is not set # CONFIG_HZ_250 is not set CONFIG_HZ_250=y CONFIG_HZ_1000=y # CONFIG_HZ_1000 is not set CONFIG_HZ=1000 CONFIG_HZ=250 CONFIG_NET_CLS_CGROUP=y # CONFIG_USB_TEST is not set CONFIG_USB_TEST=m # CONFIG_DEBUG_PREEMPT is not set # CONFIG_PREEMPT_TRACER is not set This will give you the full differences: diff -ur /usr/src/linux-obj/x86_64/de{sktop,fault} | less Regards, David Bolt -- Team Acorn: www.distributed.net OGR-NG @ ~100Mnodes RC5-72 @ ~1Mkeys/s openSUSE 11.0 32b | | | openSUSE 11.3M3 32b openSUSE 11.0 64b | openSUSE 11.1 64b | openSUSE 11.2 64b | TOS 4.02 | openSUSE 11.1 PPC | RISC OS 4.02 | RISC OS 3.11

You'll want > to have a non-proportional font to view this properly: <snipped kernel diffs> Do I understand that some groups stuff is disabled? In a lot of instructions for vbox the group settings seemed crucial... Also usb stuff missing? Missing things in those two could explain it.
