Fedora Installation :: PAE Kernel Installed By Default Now?
Jun 10, 2009
I've just downloaded F11 i386 installation DVD. I installed it on my laptop and just now noticed that PAE kernel got installed. Isn't PAE for systems with RAM >3.2 GB? It's a pretty old laptop (P3, 256MB ram). So, is PAE kernel ok for me or should I reinstall from scratch and use some specific switches in the installer to get non-PAE kernel? I've also read that Yum doesn't recognize PAE packages dependencies and will install non-PAE kernel modules if I try to install let's say Nvidia driver or so.

During tests with 11.04, I met very big problems on my HP ProBook 6550b, which is all intel , but rather recent hardware, so it is 64bit. When I install ubuntu, the -pae kernel is installed by default. All did work so far with 10.10, but with 11,04 I get frequent crashes, particularly all kind of browsers will crash every few minutes, no way any flash will work, also office seems to freeze the system very frequently.
This regardless if the 11.04 is run from life CD or installed properly. Somewhere I read, that such behavior was cured when the -pae kernel was replaced by its normal (non -pae) variety. On a very old toshiba, with some old celeron, I may not have the initial performance, but crashes are 90 percent less frequent, as there ubuntu chooses non -pae kernel automatically. Therefore I am thinking the -pae kernel could be the problem.

I installed F14, then dropped in my passwd, group, and shadow from F9 w/o backing up
what F14 had done. So now I get some messages about missing users like rtkit
and missing groups.
Is there an easy way to find out what default users and groups F14 would have installed?

I already know how to replace the kernel used to boot up the cd installer. /kernels directory. What I really would like to know is, is it possible to replace the kernel that gets installed by default with my own kernel build? Currently I have my kernel placed in the /kernels directory and that works fine for startup and installation. But then when I boot off the hard drive the kernel that is being used is not the one I placed in the Kernels directory.

I am installing to an empty hard drive (that for some reason is shown as /dev/sde - I don't know if it is related, but seems weird - why is it not sda, and moreover, not hda - it is an ide drive), and install goes through fine, but in the end it says "no kernel packages were installed, your grub configuration will not be changed", and the only option is to reboot. After rebooting, I get thrown into grub command prompt, and have no idea what to do there.

I'm taking a class this semester on Linux and a Fedora 13 DVD came with the book. Just now I've installed Fedora at home and started the updates. I saw a PAE entry in the updates so I went to the Terminal and typed uname -r and I see that the Fedora 13 DVD installed a PAE kernel on my machine that has only 1 GB of RAM.
Why did it do that?
Can I swap out the PAE kernel for a non-PAE kernel? (edit- I'm a Linux noob so I don't know)
Does it really matter?
After the updates I was going to try to install the proprietary Nvidia driver.

I am trying to install Fedora12 on a usb hard-drive, the first problem I encountered was that the hard-drive would not boot stating "kernel panic: unable to create root device", this is just using the standard fedora 12 install and mostly clicking next (although I add my vista to the grub and tell grub to install to /dev/sdc which is the location of my usb hdd).
I have also tried livecdtousb (wont boot in stick and wont recognize removable hd as removable)
I have tried setting up disc encryption and installing with no LVM.
The drive has this same problem with ubuntu 9.10 however ubuntu 8.10 installs perfectly and I am guessing earlier versions of fedora will too. The problem is that I would like the kernel features of Fedora 12 (mainly modesetting) without this issue.
I have played about with grub and quite like disabling LVM and using the uuid of the drive to select the root partition, my boot partition has 500mb, I have a 2gb swap space 50gb ext4 root partition & 27gb fat32 partition code...

Since I had problems with Openoffice since the upgrade to 9.10, I've tried to uninstall all openoffice. I've searched for 'openoffice' in synaptic and uninstalled all thet I've found. It has uninstalled many other things, thunderbird, firefox and god only knows what other. Now, there is a way to know what are the packages installed by default? Or, to install all the dafault packages? Or, there is a log of what I've uninstalled?

I installed fedora 12 very recently after which I installed a few files. I don't know where these files get installed. Is there a default location for newly installed files?
If there is one, is it possible to change the location?

After Upgrading to 11.04 32bit, the PAE Kernel loads by default. This would be great except it hangs probably due to graphics not loaded properly.
Regardless I do not want to use PAE Kernel on this dev system I have and luckily it looks like the Generic Kernel of the right version is in a sub-Menu called Older Linux Versions.
I have played with Grub2 before making minor changes but this one is a little beyond me. How can I move the regular Generic Kernel from the sub-Menu and make it my default Grub2 kernel so I boot to it automatically.

I just want to know what is the default Fedora 32 bit kernel - does it support more than 4G memory. I would like to save myself from compiling custom kernel and all following fiddling (nvidia drivers, virtualisation software etc) and 64bit OS is not for me - too many apps that I need are missing, of poor quality or need more manual intervention. Actually if bigmem / whatever it is called is configured in the default kernel, this may be the reason to switch. I intend to use 4 to 8 GB memory and it's a desktop, so server builds (like Ubuntu) are not for my taste.

Lately when Fedora 12 updates the kernel it defaults to the last kernel entry and not the newest one. However I set grub to boot entry 0 as the default which is allways the new kernel. It runs like this fine until the kernel updates then it seems to change from 0 to 1 on its own is this a new planned aspect of the new kernel being installed?

I downloaded the full desktop .iso and burnt it to a pen-drive. Firstly I installed it on my main laptop and it runs flawlessly. With the Aspire One however, though it boots into live mode and works well, after installing and rebooting all I am left with is a flashing prompt in the top left hand corner. I left it for up to an hour thinking it may be slow to boot as its a fresh install but nothing. I booted again into the live distro and checked my hard drive. As far as I can tell everything is there. So Ubuntu installed which made me think the problem was with grub. From the live cd I installed grub using the commands:
>mount | tail -l
>sudo grub-install --root-directory=/media/0d104aff-... /dev/sda
I rebooted but now I only have the grub prompt. When I type boot I get a warning saying that the kernel needs to be installed first. So why is 10.10 not booting? What else can I do to fix this problem?

Yesterday the updater installed a new kernel, Fedora (2.6.35.11-83.fc14.i686). This kernel will not boot into a GUI. This is almost certainly an nvidia problem. This kernel, Fedora (2.6.35.10-74.fc14.i686) works fine using the rpm-fusion supplied nvidia drivers. How do I get the new kernel to boot?

I installed Ubutnu 9.10 Server on my Dell Server for LAMP & OpenSSH server. After the install was complete, I noticed the the kernel installed on the server was 2.26.31-14-generic instead of 2.26.31-14-server.I am wondering why would generic kernel be installed from ubuntu-server 9.10 cd? And how do go about chaning to server kernel? Or do I even need to do that? Would generic kernel work as server kernel ?

I've a PowerMac G4 MDD that has OS X Leopard on it. I have repartitioned it to accommodate an Ubuntu install. However, I have no Disk Drive in the G4, it was broken so I removed it. Now I have an iBook G4 I have tried using an ubuntu cd on to install to the said PMac in TDM, but of course after reading the Ubuntu kernel doesn't support install to firewire by default. Can someone help me by compiling a Cd image I can use to accomplish this or tell me how without the use of another linux box?

after upgrading to lucid lynx ubuntu doesn't boot with the new kernels 2.6.32-22-generic and 2.6.32-23-generic (also in recovery mode). But it's does boot with the previous 2.6.31-21-generic kernel. At the time i was hoping to wait it out, but a new kernel has come and the problem persisted. I've been trying to find a solution for this but somehow, amid lots of failed boot blank black screen threads, i didn't relate to any solution. The boot seems to go well until a pixelated logo appears (before the login screen), then goes to a blank black screen and there it stays stuck with no remedy. Looking into dmesg logs - albeit some differences between 2.6.31-21 and the newer 2.6.32-23 - the failed boot seems proper in both logs. In Xorg logs the differences are bigger but i cannot pinpoint a source for this problem.
