Ubuntu :: Grub Screen Changed With Each New Kernel / Why Is So?
Jan 3, 2010
I have been learning about Ubuntu since 8.10. I have my two computers running dual boot (W7 + 8.04 & Vista + 9.10).
Sorry if this is a noob question, but I have noticed that each time there's a new kernel (now I have 2.6.31.16-generic), the grub OS selection screen adds 2 lines:
- One for the new kernel
- One for the new kernel - recovery mode
So, since I installed Karmic (2.6.31.14) Ubuntu Update has added 4 rows and shows code...
What is the rationale behinf this?
Why would I want to boot using the previous kernel versions?
In my laptop, it's GRUB 2. How can I eliminate the unused options?

I have installed 2D Unity 11.04 on an old desktop PC. This afternoon I tried a newly burnt Fedora 15 disk just to see if Gnome 3 would run (no luck, better graphics needed, started in Fallback Mode). Anyway I tried the live Fedora disk out for a while then ejected it and rebooted to restart Natty. I was surprised to see the Grub screen now has an earth/space theme background with Debian logos. What happened to the default purple background? Natty booted as normal and I have not installed Fedora to the hard drive.

At the moment I am using kernel 2.6.31-14-generic. I'm not one of those people who needs to have the latest and greatest kernel to be happy, I just rely on the update manager. I swore that I saw an update for a new kernel, but my kernel version hasn't changed. I'm just curious if there was a new kernel that was released or if that was just an update to the kernel listed above.

I recently installed virtual box on debian and after it had finished my terminal informed me that I could remove some "unnecessary" software by use of sudo apt-get autoremove. When I did this, some of the icons on the desktop changed and all of the icons in the drop down menu on the bar at the top of the screen also changed to ordinary folder symbols. The theme that I was using also went away. I restarted the computer and it booted back into a shell prompt with no GUI. I tried to get back to the GUI using alt+f7 but it didn't seem to exist

I tried to update to 2.6.31-20 kernel but I think I messed it up, because when I click on it in the GRUB it starts to load but then it goes back to the dell boot up screen and I have to use the older one in order to get onto ubuntu. Is there anything I can do to fix this?

After a fresh install of opensuse 11.3 and a xen-hypervisor and tools (all default install, nothing special) just get a black screen when I try to use kernel-xen. Default kernel runs like a charm. Xen-kernel gives me a black screen just after grub menu.
This is my menu.lst about it:
###Don't change this comment - YaST2 identifier: Original name: xen###
title Xen -- openSUSE 11.3 - 2.6.34-12
root (hd0,2)
[code]...
I have no nvidia card...

I upgraded my ubuntu version 8 to 10.. I was using my new version normally, but on the GRUB screen, I have two choices (ubuntu 1 and 2.. something like 'generic-2.6-32..) I could only choose the second option.. because the first option, return this error: you need to load the kernel first.
Ok, i'm using the second option... but when i'm tried to install the driver of my nvidia 3d board, the second option of boot is also not working.. =(return this erros: kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block (8,33)... both are kernel problems.. my instalation of ubuntu 10.04 was perfectly successfully (aparently)..

I am using kubuntu 9.04 dual booting with winXP. The package kit showed that I have 179 bug fixes. So I updated them.Now the boot time grub menu shows 6(two different versions for kubuntu and kubuntu recovery mode) entries instead of usual 4(winXp + kubuntu + kubuntu recovery mode + memtest). My grub.cfg file is as follows:
Quote:
#
# DO NOT EDIT THIS FILE
#
# It is automatically generated by /usr/sbin/grub-mkconfig using templates
# from /etc/grub.d and settings from /etc/default/grub
[code]....
What is wrong. How can I change the entries. Which one to remove ?

in 11.1 (2.6.27*) there were occasional kernel msgs generated in the "messages" log:May 26 21:57:28 blkdragon kernel: TCP: Treason uncloaked! Peer 188.48.28.209:18769/58845 shrinks window 2778476289:2778478629. Repaired.had to do with torrents/java and azureus/utorrent, with the outside ip number/port assignments easily understood and parsed if necessary.in 11.2 (2.6.31.5) the same type of entry is:00:24:23 blkdragon kernel: [258668.819024] TCP: Peer 0000:0000:0000:0000:0000:ffff:54b6:489e:10858/44949 unexpectedly shrunk window 3076383191:3076383869 (repaired)

my Setup is Fedora 14 x64 + radeon hd 4830 i've downloaded .run package from ati site with latest driver for x64 systems. installed it, but didn't edited grub.conf becouse i didn't understood anything there (probably didn't spent enough time to get things understand) Now i've lost possibility to enter my Fedora system. during boot it lost it's modern blue boot screen (with filling drop), it was replaced by standard old boot screen with triple-color stripe. after this boot screen monitor start blinking going on and off. and on last step i'm getting "Fedora 14 boot bla bla bla something" on screen. nothing works except Ctrl+Alt+Delete. system reboots showing successful daemons shutting sequence. How can i edit grub menu from initial grub screen is it possible to it's own 'e' option or 'c' from grub command line?

We had a server failure this morning because grub was throwing error 15 (file not found). We discovered that the disk had changed names from hd0,0 to hd1,0. Making the appropriate replacements in menu.lst fixed the problem, but I'm still wondering what could have caused the spontaneous name change.
here are some other possibly related tidbits: * the server had been down because of a power loss, but it is behind a UPS so i doubt there is any electrical damage * eth0 also temporarily failed but the system failed over to eth1
My current theory is that when the bios was configuring the hardware the loss of eth0 shuffled around the addresses of the remaining hardware on the pci bus, which somehow caused the hd0/hd1 confusion. The problem is that everything i've read [URL] says that the drive assignment should be based on the way the disk is connected to the motherboard (which in this case didn't change)

When I first installed openSUSE 11.4 the /boot directory looked like this:
I had installed VirtualBox through Yast and decoded to delete. After deleting the /boot directory looked like this, pointing now to the desktop kernel.
I went into YAST and deleted all kernel entries that contained desktop, trying to get back to the original configuration.
After doing this, the /boot directory now looks like this.
Is there any way to get back to the original kernel configuration without having to do a complete installation?

I use the on-board sound chip of a Gigabyte motherboard (Realtek)and I have connected it with optical cable to an amplifier.
Everything worked fine, until February, when an update changed the kernel and the PC stopped giving sound signal! When I returned to the previous kernel (at grub), again everything worked. So,it doesn't seem to be a connection or drivers problem.
I supposed that with 11.04 edition this problem would be solved. But it isn't. In fact I have serious problem now because the old kernel isn't listed in grub anymore.

That's a picture of my ubuntu 9.1 64bit login screen. The background image I changed myself months after this problem started, so I'm sure that has nothing to do with it. What I DID do that caused this problem was follow the openoffice dark theme fix on this page:[URL]
BACKGROUND: I installed a dark theme that made the openoffice word page black, so I had to find a fix for it on the page above. I'm not using the theme anymore, but it was "Slickness black" on gnomelooks.
In case someone didn't see a problem with the orginal login screen, the section where you click the username and enter your password should look like this:
Also incase anyone was going to ask, my login DID look like the second picture at one point (before the openoffice fix) I just removed openoffice completely and reinstalled it so that isn't the solution.

I've been using Ubuntu for about two years now, then suddenly today (after my PC accidently lost power) the screen resolution changed to 800x600 (it is, in fact, a widescreen monitor, and this resolution looked 'zoomed in'). The only two resolutions detected with xrandr were in the 4:3 ratio (800x600 and something worse). I followed some instructions, trying to reset the resolution to 1024x576.
I got as far as
$ xrandr --newmode "1024x576" ...
then,
$xrandr --addmode default 1024x576
but when I
$xrandr --output default --mode 1024x576
I a message to the effect of 'your screen can only support 800x600 or less'. Ah-ha, I thought, you stupid machine; this screen has had a greater resolution for over a year.
And so, from System->Preferences->Monitor, I forced the computer to switch to this new resolution. When prompted, I reset.
My current problem is that when I turn the computer on, the monitor displays a floating 'Input Not Supported' sign. I Ctrl+Alt+F1'd, and now all 'xrandr' and 'cvt' commands return:
Can't Open Display
My first priority is to get the computer back to it's less-broken 800x600 state;
EDIT: I'm running Ubuntu 10.04

A few minutes ago, I was connected to my remote machine running Ubuntu 10.10. I changed the resolution of the screen while connected with VNC, but now I can't connect to the remote machine. How can I fix this without leaving my house?

How do I force recompilation of the kernel .deb packages. After a small change I make to the sources without having to clean the sources and recompile the whole kernel again?
Code: Select all$ fakeroot make -f debian/rules.gen setup_i386_none_686
$ fakeroot make -f debian/rules.gen binary-arch_i386_none_686 binary-indep
Calling the second command again does not recompile the modified code, just recreates the .deb packages.
If I use:
Code: Select all$ make -f debian/rules clean before the build command, then it will recompile everything which takes ages.
How can I force recompilation of the files/objects I changed (and dependencies)?
I use this guide: [URL] .... ('Building only a single kernel variant' section)

im having an intel E2180 processor with 2 gb RAM and an nvidia 8400gs graphics card. Lately i installed Fedora 12 on my system and found that with default settings the desktop 3d is not working. so installed the kmod-nvidia using yum after following the instruction.i also edited the grub.conf file to rdblacklist=nouveau to blacklist nouveau drivers.
Then once i rebooted i found two kernels in grub ie the old one and the one with PAE extension. when i booted into the old kernel its Xwindows failed to load showing a black screen and when i tried the new PAE kernel it booted in 640 x 480 resolution. {earlier i was getting a resolution of 1440 x 900 on my 17" widescreen monitor}. it also showed that the nvidia drivers failed to load. I also read in some forums that the PAE kernels are for systems with 4gb+ of ram. So i thought it better to reinstall the whole thing.
then i reinstalled the whole operating system using my fedora 12 dvd and performed the 'upgrade or replace the existing linux distribution'. interestingly now my older kernel has disappeared and the PAE kernel is the one that is remaining.

I recently installed my first distro, Gnome Ubuntu Linux 10.04 via WUBI dual-booting alongside my Windows. I decided to try the other desktop environments. So I installed Kubuntu-Desktop (KDE) and Xubuntu-Desktop (XFCE) using Synaptic Package Manager.
However, Kubuntu KDE changed the boot splash screen into a from the default Ubuntu one, to the Kubuntu one. Also Xubuntu XFCE changed the log-in screen to the Xubuntu one. I DO NOT want these changes. I just wanted Normal Ubuntu-branded Ubuntu Linux with the option of logging in into the desktop environment of my choice.

I changed may graphic card, earlier I used NVIDIA FX5500 with nvidia driver, now I was trying to use ATI Radeon 7500, but there are problems with graphic configuration. At first attempt server started but after I changed a screen resolution the monitor went blank. I restarted a computer but after the X server started immediately the monitor wnet blank. I found that for completely for me unknown reasons Xorg was trying to use an NVIDIA glx module with radeon driver. I removed this nvidia driver, I expected ubuntu would be able automatically to set up a proper configuration, but instead of ubuntu complained about a missing driver. I also tried manually to set up some basic config using Xorg -configure but after that the Xorg server was stuck.
