Kubuntu 9.04 64-Bit, Kernel 2.6.30.1, and NVIDIA…

I went ahead and decided to upgrade my kernel, and to go to the latest NVIDIA driver (180.51).  I downloaded the kernel and the nvidia driver file, built the kernel, and removed the nvidia restricted driver.  This is on a 64-bit build of Kubuntu 9.04.

However, I was not done.

When I tried to install the kernel image file, I kept getting dkms errors relating to nvidia-common.  I eventually removed the nvidia packages using “apt-get remove --purge nvidia*” (as root), but this still would not allow me to install the kernel. Also my xorg.conf file was empty.

I fixed xorg by typing “dpkg-reconfigure xserver-xorg” and adding in the line “Driver "vesa" ” to the “Device” section, so I would have something when I rebooted.

Only when I removed dkms (“apt-get remove dkms“), was I able to install kernel 2.6.30.1.  I use lilo since I run RAID-10, but did not have to update the /etc/lilo.conf file.  Upon reboot, I stopped X with “/etc/init.d/kdm stop“.

I next installed the NVidia driver first (and chose to install the 32-bit compatibility files as well). After that, I ran “nvidia-xconfig” and my xorg file was ready.  When testing with the “X” command, it just pulled up a blank screen, but I took a chance and started KDM (“/etc/init.d/kdm start“).

Everything came up fine.  Typing “glxgears” in a terminal showed decent enough acceleration (about 3000 fps).

So far, no other ill effects. And no firmware issues.

Kubuntu 9.04 and Flash Audio…

I finally got sound to work reliably.  Here is what did NOT work:

  • “touch .asoundrc” in the home directory
  • remove and reinstall non-free flash and the installer
  • ensuring the PCM channel was unmuted and not turned down

I did have to make sure that the correct sound card was selected (I have two).  This made a difference for system-wide purposes, but as far as flash went, sites like YouTube were mute.

I finally found a site that gave instructions to install a pulse audio management tool – padevchooser.  I don’t remember which site, because I must have trolled dozens, but this solution worked every time (I had to do this once for each user, as each user).

Opening a terminal and running padevchooser opened up the app in the system tray.  Left clicking it brought up the context menu.  Selecting Volume Control, and the Output Devices tab, I was able to ensure that the correct card was the default.  On the Playback tab, I was able to move the stream to the correct card.  For some reason, they all seemed to default on the other unused card, which is integrated into the motherboard.

Once I did these things, Flash audio was just fine.

Dual-boot Laptop – Vista and Kubuntu 9.04…

I started last night.  First, I decided to use the 32-bit LiveCD installer.  I booted off the CD after shutting down Microsoft Windows Vista Home Premium, and soon was at the GUI (I chose the first option; to test before installing).  Once there, i opened up a konsole session, ran “sudo -i” to get root, and installed gparted – “apt get install gparted”.  After it installed (to RAM of course), I ran it to see what I could do.

NOTHING.

I could not resize the 140 GB partition Windows called a “C drive”, because I forgot to defragment it first.  Crap.  So I booted back into Windows, Safe Mode.  I found the defrag tool under the System Accessories, but it would not run.  I tried from the command prompt as well.  I rebooted, into SAFE Mode With Console, and it still wouldn’t work.  I finally just rebooted into Vista normally – then it worked.  It gave no status other than a flickering hard drive light and a spinning cue that meant it was not finished.  Eventually, it did finish.  It claimed to have been doing it on a schedule, and the last defrag was back on the 5th of May, yet it took over two hours to complete.  Guess what?  It made all the difference in the world.  I suspect it wasn’t really defragmenting after all.

Once I rebooted into Kubuntu Live CD and reran gparted, I was able to resize it.  The first attempt failed – I cut it too close to the bare minimum space i could shrink the drive.  I decided to split it 50-50, giving about 70 GB for each side, and then it worked.  This took another hour, but I had 70 GB or free space.  I went into cfdisk and manually made a 10 GB bootable partition for root, a 3 GB for /var, a 2 GB for /tmp, a 2 GB for swap, and the rest for /home.  i then rebooted into Windows.

Windows behaved as expected, like it had been punched int the mouth, but didn’t know by whom.  It rescan itself, determined that everything was still ok, and rebooted again.  This reboot came up fine.  Satisfied I had not broken Vista, I rebooted a final time back into the Live CD.

I went ahead and formatted everything with XFS except the swap partition:

  • mkfs.xfs -f -d agcount=1 -i attr=2 -l lazy-count=1,size=128m,version=2 /dev/sda3
  • mkfs.xfs -f -d agcount=1 -i attr=2 -l lazy-count=1,size=128m,version=2 /dev/sda5
  • mkfs.xfs -f -d agcount=1 -i attr=2 -l lazy-count=1,size=128m,version=2 /dev/sda6
  • etc…

I then made the swap partition and then installed, choosing to manually select my partitions and not to format them.   I went to bed, abd when I woke up and checked in the morning, it was done.  I had been unable to get wireless to work (no proprietary drivers needed, just would not work) on the Live CD, so I had connected it up via network cable.  Once I booted into the new system, I saw that it had a GRUB entry for Windows (it works).  After logging into KDE, I was able to set up a working wireless connection with no real drama.  I also modified my /etc/fstab to mount the XFS partitions with the following options:

noatime,nodiratime,logbsize=256k,logbufs=8

I edited /etc/X11/xorg.conf and added in the section to reenable the CTRL-ALT-BACKSPACE zap for X:

Section "ServerFlags"
      Option          "DontZap"               "false"
EndSection

I installed the medibuntu repositories, the kubuntu-restricted package, the sun-java6 package, the non-free flash package, the libdvdcss and libdvdread packages, lots of TTF fonts, the MSTTF core fonts, skype2, firefox, thunderbird, and the packages needed for a DoD smartcard.

Xorg no-zap

Results:  It boots and shuts down much faster than Vista.  It is a Compaq lapto, Pentium Core-Duo, 1 GB RAM, uses the ath5k driver for wireless, has an integrated Intel graphics adapter (maybe 800 fps max on glxgears), and a 160 GB SATA drive.  It has sound, a mic, speakers, a DVD writer, some USB ports, and a network jack.  Overall, not too bad for what I need it to do.  But it is a little shaky and unstable from time to time, so I have shut off the compositing effects and unloaded some troublesome widgets (RSS news widget especially seemed flaky).  But the suspend and hibernate functions work great, and the webcam i bought (Logitech) worked right off the bat with skype.  So did my smartcaard reader.  I also installed the Acrobat Reader from the Adobe website – with it, I added the coolkey security device and am able to sign fillable PDF files with my card.  DVDs also play (region-free, of course).

So, these are my ramblings on the notebook.  I dual-booted because my wife insisted I keep Vista, just in case the Linux machine she is on dumps.  But she is getting more comfortable without Vista already – I can tell.
