Fixing Ubuntu 9.10 Karmic Koala boot drops to grub shell without showing boot options

Dec13th
2009 Leave a Comment Written by Bharath

I had this problem with a wubi install. Ubuntu would highly pester me and drop to command shell (that of grub) without showing the boot options (Why and who knows??). I every time will have to boot by manually entering boot options (really painful).  So I did this.

I entered the boot command of the “recovery console” manually by finding it out from grub.cfg through the Live CD. After getting to the repair option I selected the option “Update GRUB”. Then the system did something I dont know. Then after returning to the options I selected the option similar to Boot Normally (whatever the exact wording was). Now, that was a miraculous finding. I restarted and boot worked like it should.

P.S-Something or the other helps me huh??

“Kernel-panic – not syncing : VFS : Unable to mount root fs on unknown-block(X,X)” error in Ubuntu

This one seems to be a really famous problem for most folks in Ubuntu 9.10 Karmic Koala. So I had it too. The problem was on the initrd file. It is a kernel related file needed for booting. So i did a simple thing.

I replaced initrd.img file of my kernel version with “initrd.lz” file from the Ubuntu LiveCD and edited my grub.cfg file (equivalent of menu.lst in older Ubuntu releases), to boot using initrd.lz

In other words, wherever there is an entry like initrd.img.2.24-16 or similar just replace it with initrd.lz and in my case I also copied over the vmlinuz file and made necessary entries (just in case). Now, am back in action with Ubuntu. :D

[How-to] Make nVidia settings persistent and retain the settings in Ubuntu 9.10 Karmic Koala

Nvidia Proprietary Drivers need nvidia-settings to set screen resolution and change other settings. In previous versions of Ubuntu and in other distros to make them permanent (used in every session) you click the “Save to X configuration file”. From Karmic on there is no xorg.conf by default!

As a result, nvidia-settings is not able to save the settings and every time I logged in I had  to change the resolution (Phew!!!). Then Sathya helped me. He gave me a link from Ubuntu Forums. Then I did the following to fix the problem:

Saw this question on SuperUser :

How can I add menu items to the Gnome “Applications” menu from the command line?

Yet another SuperUser Q

RSS Feed Notifier for Linux

Seems Canonical will set limits to those who can order free CD’s via Shipit.

The discs will still be made available to Local Community team members and Ubuntu contributors. And new Ubuntu users will be able to request a CD. But you need to create an account and sign in to request that CD. In other words, Canonical will be tracking you and will only send you a free CD the first time you ask for one.

Some tips on Ubuntu 9.10 Karmic Koala

Something about Microsoft patenting sudo

Here it is, patent number7617530. Thanks, USPTO, for giving Microsoft, which is already a monopoly, a monopoly on something that’s been in use since 1980 and wasn’t invented by Microsoft. Here’s Wikipedia’s description of sudo, which you can meaningfully compare to Microsoft’s description of its “invention”.

MPlayer Now Supports Most HD-DVD/Blu-Ray Codecs.

The latest MPlayer code in their SVN trunk now supports most HD-DVD and Blu-ray codecs. Earlier this year we talked about possible Blu-ray support for FFmpeg and developers becoming more interested after we interviewed the FFmpeg developers and there ended up being an outpouring of support by our readers offering up Blu-ray drives and other forms of help. The latest MPlayer code in their Subversion repository now supports most Blu-ray and HD-DVD codecs.

Fix for Ubuntu (and other suitable OS) hanging during boot with nVidia GeForce FX 5200 (and other suitable cards)

Nov10th
2009 2 Comments Written by Bharath

This is one problem that has affected me the most in my history of Linux usage, so far. Imagine, for two full years I just din’t know that the solution to this problem is so simple. Too late of me to find out. Anyway, better late than never.

So the problem is, with my graphics card GeForce FX 5200, Ubuntu liveCD/post-installation boot will hang mid-way, with the boot-screen freezing or a big set of hexadecimal codes getting emitted. The cause is that ACPI settings, making some conflict (I suppose), with the Intel On-board Chipset. The “acpi=off” bppt option does NOT work in Ubuntu. Now, that’s what everyone suggests only to know it never helps. (Even Sathya suggested it to me)

It does not work because, BIOS settings dominate at the boot time. In other words, boot takes place by the settings in BIOS.So, the Ubuntu boot option “acpi=off” makes no sense. So, now does it become clear? You disable ACPI in BIOS!  Wow, that worked like magic for me. Now I am running Ubuntu 9.10 (Karmic Koala) on my PC without any boot problems.

However, shutdown does not work properly. Other things like restart and general things work fine.

So try that comment on whether it works.

Presenting 915resolution — Fix for Intel Drivers

Nov9th
2009 1 Comment Written by Bharath

This article appears too late i suppose in this site. Many know about it already. Just in case, i am posting it.

So if your xserser-xorg-video-intel is not that satisfactory to you, or if it doesn’t give the right screen resolution, just use this. If available in repos use it, if not use this link. You will have to remove xserver-xorg-video-intel either manually or through package manager. Then after installation restart Xserver (Ctrl+Alt+Backspace; Enable it thus in Karmic)

That should bring the resolution right or at least make it better.

Thanks to these articles and in case of problems please follow the links:

In Karmic the restart Xserver shortcut is disabled by default. Enable it thus:

1. In the menu, go to System->Preferences->Keyboard (not Keyboard Shortcuts)

2. Go to Layouts tab, click Layout options

3. Expand “Key sequence to kill  the X server”. Check “Ctrl+Alt+Backspace”

4. You’re Done.
