kernel compilekernel kernelcompile kernelhowto customkernel	<reply> The core of Ubuntu is the Linux kernel: see https://help.ubuntu.com/community/Kernel - You shouldn't have to compile your own, and if you need to troubleshoot issues, you can try a !Mainline kernel instead, but if you insist, see https://help.ubuntu.com/community/Kernel/Compile (see also !Stages)	Added by apokryphos Date: 2006-06-18 22:01:25 Last edited by IdleOne Date: 2011-04-10 12:12:54 Requested 3536 times

fuse captive	<reply> FUSE (Filesystem in Userspace) is a !kernel driver that allows non-root users to create their own filesystems. See http://en.wikipedia.org/wiki/Filesystem_in_Userspace for more on FUSE. Some examples of filesystems that use FUSE are !ntfs-3g, sshfs and isofs.

stages	<reply> The Ubuntu Kernel gets updated in stages. If you have the updated kernel, but do not have the corresponding restricted modules, you may be leaving yourself with no X when you reboot. If you have compiled binary versions of your video driver, eg from the nVidia site, you will need to recompile them for the new kernel. This is normal, and not a bug.

amd ati fglrx amdgpu	<reply> On Ubuntu, AMD's official Linux graphics driver "amdgpu" is automatically loaded for matching hardware. Very old cards use driver "radeon" (r300, r600) instead. See the !man pages for X options, "modinfo -p <graphics-driver>" for kernel parameters. Both drivers are open source and integrate with MESA and !DRI. Drivers "amdgpu-pro", "fglrx" and "ati" are not supported here.	Added by knome Date: 2015-08-03 19:17:31 Last edited by tomreyn Date: 2022-06-17 18:21:56 Requested 170 times

highno	<reply> A higher version number does not mean that it's better. Especially with packages such as the linux kernel. The packages in the Ubuntu repositories are stable and will work fine. You should have a better reason than "newer" when considering compiling from source or using 3rd party repos.
