Ubuntu Installation :: 11.04 PAE Kernel Loads By Default?
Apr 28, 2011
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.

Recently, I upgraded 11.1 to 11.2. Everything seemed to go fine. However, for some reason the system boots with the debug kernel - 2.6.31.5-0.1-debug. According to Yast every kernel under the sun seems to be loaded on the system. Grub, however, gives two choices - one for the regular and one for the failsafe system. They both boot to the debug kernel.
How do I get this thing to load into the regular, as opposed to the debug, kernel?

If I do try to start a PXE Installation, the PXE Bootsystem loads the kernel, and
I guess it trys to start to load the initrd, but then it froze, i need to reset the computer. On the TFTP Server (aftp) I see that it trys to resend the initrd files and runs into a time out.
Ive the problem on 2 maschines, both with the same Motherboard (ASUS M4N78).
And the PXEinstallation of OpenSuSE 11.3 works fine, without any problems.

I put in latest Ubuntu 11.04 CD, and clicked "Try Ubuntu". It loaded Gnome desktop environment. I thought Unity is default now, at least that's what it says on Ubuntu website. Why I got Gnome. And when I install Ubuntu, how do I switch between this two? Are applications compatible?

There seems to be nothing in Preferences or anything, but after the other night, all new windows load in semi-full screen, where the File-Edit-etc menus are there, but the bar at the top isn't, and the taskbar at the bottom is covered by it. Its what happens with certain annoying ads, but now its any window.

In Ubuntu 11.04, grub skips directly to booting Ubuntu. I can't choose which kernel image it loads. Why is that and how can I fix that?

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'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.

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.

differences between Kernel Default and Kernel Desktop? I've found some past threads like this link and this other link, and some other google info, which suggest the only difference would be the io scheduler. Also, I see the default grub choice is "Desktop" and not "Default", so I take this as a suggestion to prefer one over the other.
However, my broadcom 4312 wireless only works on the "default" and not on the "desktop" kernel, so I guess there must be other differences. I just want to evaluate which one is the less long-term risk option to go.

I upgraded 10.04 to 10.10. At the tail end of the install, the display locked. After an hour or 2 I rebooted the box.
Came up to a command prompt (instead of starting the GUI automatically), started the GUI, everything seemed fine.
Ran 10.10 fine for 2 days. Installed apps, got my SVN environment set, started doing development work.
I got a lockup, had to reboot....Came back as 10.04.
I have only one hard drive (/dev/sda), 4 partitions.
My new files all seem to be there, are accessible and valid. Just the OS version has reverted??!?!?!?
How do I get back to 10.10 (without doing another update, install cycle)? Surely it's there somewhere...
Looking at the grub list, only Ubuntu 10.04 is an option.Looking at the /boot directory, there are several initrd.img files that are newer than the ones associated with 10.04 in the grub/menu.lst file (i.e., Ubuntu 10.04.1 = initrd...2.6.27, whereas there are other files in the boot directory like 2.6.26, 2.6.31 and 2.6.32)

After installing ggobi from the Lucid repositories, I get a bunch of errors on running it, all to do with not finding plugins, e.g.** (ggobi:10070): CRITICAL **: Error on loading plugin library plugins/ DataViewer/ plugin. la: (null)Sure enough the plugins aren't available when ggobi loads.

The problem is I've set up a dual boot with Xp and Ubuntu 10.04. Ubuntu was working fine till 2 days back but now when I select Ubuntu from the grub screen i get a whole lot of numbers next which it'll say Usb drive or sd card reader etc.. these go by quickly and then the comp stops running. If i press enter on the keyboard I get Initramfs and then i can type but nothing happens even if I type reboot. if I press cntrl+alt+F2 then i get a blank screen with flashing cursor. Same with recovery mode. Windows boots fine. The grub2 screen comes fine. The last thing i did before this happened is reconfigure the grub2 screen, but it seems to be fine (i had added a background img and reordered the boot options) I did not edit grub.cfg. I would prefer not to reinstall it as iv done it a half a dozen times already in the last few weeks..

I am trying to install 9.1. On bootup the CD loads and gives me the options on Installation, Try Ub etc. However after I choose install the BW logo shows up but nothing happens after that.
Incidentally i have 2 of these machines with 9.1 and 10.04 installing fine in the other one. In this one the main difference is a newer DVD burner. The other one also has a DVD burner but older.
The DVD burner is about 7 months old - purchases earlier in the year.
So wondering if loading the driver is an issue? if so how does the CD load and even the logo loads after Install is selected?
Or is it a different issue and would there be different options to try when installing? I would rather not have to replace the DVD burner.

Ive installed Ubuntu 10.10 from a SD card (yes my laptop supports booting from SD) and it works fine except the grub does not load. Although I know there are many threads about this Im not sure which one to use because my problem is quite strange.
Im not pretending I understand how grub works but I find it strange:
When I boot from Hard Drive, it boots into Windows without loading grub (I installed ubuntu to an empty partition along the windows on the same drive), however, when I force booting from the SD card, I get the grub window with all the options as expected - ubuntu, mem check, windows 7. Now Im not sure if its grub loading from this SD card (containing ubuntu) or the card somehow runs the grub that is on the hard drive.
My guess is that the partition containg windows (sda0) is flagged as boot and thus the system doesnt even look after grub when booting, however, when theres the SD card it somehow forces booting the ubuntu partition (sda6).
Any idea what I should do? I can boot into Ubuntu, I can access grub etc. I just cant make it load without having the SD card in my PC

How do you change the order of the list? I have Xubuntu 9.10 installed on a 5 gig partition. I only use it for Skype as the mic does not work in 10.04 at the moment for me.Anyway, I would like 10.04 to default to the top of the list. How do I change the order when grub loads.

I'm getting a tad frustrated. Having gone down a dead end on this thread: [URL] I reloaded 10.10, wiping out previous install. Everything was working as it should. I then updated (today, Sept 16, 2011) When rebooted, the system went right to a grub prompt.

i just installed the Debian on my old laptop. The install went fine but after that, the GRUB menu loads and freezes. I simply can't do anything. I checked menu.lst and the timeout is set to 5 but still nothing happens. It won't load. I then tried to load with the "super GRUB disk"but the same problem - as soon as it loads from the CD, it freezes and I can't do anything. Before I had Xubuntu on the same laptop but there was no Grub menu. It simply loaded. There's only 1 OS on the laptop /currently Debian/ - no windows, no other Linux.

this is the 3rd time in 2 days I have installed this OS and its starting to annoy me. I have a Intel Celeron 2.6Ghz with i845 graphic chipset. I have installed 11.2RC2 and after the installation finishes and I reboot, it automatically asks which resolution I want (VESA/VGA). I have to select VESA since the VGA resolutions are HORRIBLY HUGE. When the boot screen comes, it loads halfway and then comes to a crashing halt. I let it load for 2 hours yesterday and it did NOTHING. After turning the computer off and back on, it comes to a screen to load normally or into failsafe. If I choose normal mode it does the same, if I choose failsafe, it does the same. So basically I have an OS I can't reach. If I could, I would give an xorg.conf on here, but I can't even get anywhere to produce one! When I put the live CD in, it boots perfectly, but I have to install again, only to get a OS that wont boot yet AGAIN.

My Wubi installation of Ubuntu (version 9.10, I think) that I recently installed was working fine at one point, but now it isn['t. I select Ubuntu instead of Windows from the Windows boot loader, but instead of getting the usual menu of different linux versions (I think 2, as I updated it at same point), and Windows, I get the GRUB command prompt instead.I've looked at th2e Wubi Guide (https://wiki.ubuntu.com/WubiGuide), and I've followed the instructions for "How can I access my Wubi install and repair my install if it won't boot?", but that reveals no problems.For the record, I'm fairly new to linux and ubuntu, but I'm good with computers generally. The main operating system on my computer is Windows Vista, but I'm currently typing this from a Live CD of Ubuntu 9.10. The virtual disk (root.disk), is currently mounted as vdisk, as indicated in the Wubi Guide.
Ideally I would like to get Ubuntu to load as it used to (with a menu). However, if there is a way to boot from the GRUB command line that would be good too. I'm not at all familiar with GRUB, and the commands I've tried (boot and linux, I think), get errors saying no kernel specified, or loaded, or something like that.

I had a dual boot working fine with XP and F12 on two physical drives, all was well. Last night my friend helped upgrade my system, I now have 3 drives (20gig F12) (60gig XP) and (320gig Win7) now the PC only loads Win7 as I think my friend told bios to boot from 320gig. Has anybody here got experience with triple boot from 3 drives? Here is my guess, tell bios to boot from other drive and add Win7 to grub. Not sure how but that's my guess. Also what worries me is that win7 does not "see" the other two drives.

I have already had Vista installed on another drive and from what i've read on the webs you get to dualboot if you install ubuntu after vista. when i did install it (i installed on a blank hdd with no partitions, choosing the "erase entire disk" option since for some reason default option was attempting to eat a part of my windows 1 gb drive instead of using disk i specially made for it) and the grub 2 loaded for the first time, there was NO option to run vista. only 2 linux (normal and recovery) and 2 memtests. I've ran linux and went to google this. I found that i should add something to some config files in /etc/grub.d/From reading the readme file i understood i could add my own files that are named like NUMBER_SOMENAME and insert code into them. Because it said:Quote: For example, you can add an entry to boot another OS as01_otheros, 11_otheros, etc, depending on the position you want it to occupy inthe menu; and then adjust the default setting via /etc/default/grub. But then i found a file 40_custom that said:
Code:
#!/bin/sh
exec tail -n +3 $0
[code]....

I'm trying to install Fedora 10 on my samsung HDTV with my PC hooked up via DVI-HDMI. All the text screens look fine, but when it loads the graphic installer, the video gets corrupted, but i have a mouse, but a few seconds later it freezes and hangs, and I can't do anything. Nothing loads. This happens with the livecd's as well.

I completed my dvd-burn for Fedora 10. I booted up from the dvd, and the automatic 10 second installation text shows up. The setup loads the images, and proceeds to a loading bar. After the loading bar I saw an underscore. That all I see.. I wait a couple of minutes and I still only see an underscore. This is my first time trying to install a Unix type O.S. Are there any commands I need to run for the installation to move forward? Or is there some type of corruption in the installation?

I just downloaded Debian's live CD .iso file. I put it on a USB stick and booted from it. It loads everything then presents me a login screen. I have no idea what the login and password is I've looked all over google and people said it was user: live pass: live or something like that. I've tried a lot of different combinations with no luck. So does anyone know the real username and password for this?

I performed a clean install of Fedora 15 from DVD and it goes fine until the end when the install program says to reboot the computer. Once I do that, the computer hangs before Grub loads, i.e. just after all of the BIOS messages, so there isn't any error message to indicate what is wrong. I had no issues with Fedora 14.

I can choose which kernel I want to boot by default, instead of having to hold the shift key down every time I want to choose the kernel I want to boot into. I am running multiple kernels.
