| orated | How can I use linux kernel 3.1 on Ubuntu 11.10? Should I try http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.1.5-precise/ ? | 19:14 |
|---|---|---|
| JanC | orated: if you want a newer kernel for some reason, that's a good place to get them | 19:17 |
| JanC | but remember that it is not officially supported | 19:18 |
| orated | JanC: I came to know that 3.1 resolved performance issues with Sandy bridge procs, so for that reason I need new kernel. So should I u | 19:18 |
| orated | ah | 19:18 |
| orated | Well, any ppa for the same then? | 19:19 |
| JanC | in that case, you might try it | 19:19 |
| JanC | this is the best place to get it | 19:19 |
| JanC | just, there is no guaranteed security updates etc. | 19:19 |
| orated | until ubuntu packages it? | 19:20 |
| JanC | those packages are actually made by the Ubuntu kernel developers, but in case of security bugs, the officially supported kernel (which is 3.0 in oneiric) has precedence of course... | 19:21 |
| orated | And what other things apart from that? | 19:22 |
| JanC | there might be some drivers missing, as those are mainline builds | 19:22 |
| JanC | drivers that are not in mainline yet | 19:23 |
| JanC | most likely because those drivers aren't very stable yet ;) | 19:23 |
| JanC | orated: you could try if the mainline builds work well | 19:24 |
| orated | https://wiki.ubuntu.com/Kernel/MainlineBuilds is there any wiki like that for 3.1? | 19:24 |
| orated | But if it doesn't than it may perform poorer than its performing now | 19:24 |
| JanC | you can always install/remove other kernels, or select a different kernel in the grub boot menu... | 19:25 |
| orated | ah, right | 19:25 |
| orated | Ok. So, this is what I'll try now and then get back to you - wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.1-oneiric/linux-headers-3.1.0-030100_3.1.0-030100.201110241006_all.deb | 19:25 |
| orated | followed by - sudo dpkg -i linux-headers-3.1.0-030100_3.1.0-030100.201110241006_all.deb | 19:26 |
| orated | right? | 19:26 |
| JanC | orated: if the default kernel doesn't work well, it might be a trade-off to use that one indeed | 19:26 |
| JanC | and I'm not sure i will be around later, but you can try ;) | 19:26 |
| orated | Ah-ok. Thanks.. I hope it doesn't mess things badly | 19:27 |
| JanC | orated: you can always hold the shoft key during boot to get into the grub boot menu, and then select a 3.0 kernel to boot if the new one is worse ;) | 19:28 |
| JanC | *shift key* | 19:28 |
| orated | Yeah, I can do that. I remember :) | 19:28 |
| orated | I'll get back, cya | 19:29 |
| orated | Hey JanC. I installed kernel 3.1 but I don't see that option in grub. I'm still on 3.0 | 19:39 |
| orated | uname -r returns 3.0.0-14-generic | 19:40 |
