UPDATED2: Quick tip: Asus A8V-VM SE and mythtv

March 2, 2009 1 comment

I am running Mythbuntu 8.10 on my Asus A8V-VM SE with a Athlon 64 3200+ and faced severe problems. The most annoying one was the problem, that mythtv periodically wasn’t able to detect the tuner cards, although they were detected by the kernel and were configured correctly.

I tried several tips like moving the daemon call of mythtv-backend in /etc/rc5.d to a later position, from S25mythtv-backend to S99mythtv-backend – this didn’t really help. Until I finally got a setup, which works now in most cases or let’s say, nearly with all bootups.

So to help you preventing one or another headache, this is my setup wich works now really well:

In the Asus BIOS, you have to disable:
APIC
ACPI 2.0 support

and in Ubuntu, you have to add

noapic

in /boot/grub/menu.lst, so that it looks like this:


kernel /boot/vmlinuz-2.6.27-11-generic root=UUID=xyz ro locale=de_DE quiet noapic

The next article I am planning will describe how to setup mythwelcome and acpi wakeup with Mythbuntu 8.10 on the crappy Asus A8V-VM SE – stay tuned.

Update:
I recently posted exactly here another socalled dirty tip, which should solve the problem – but as I have faced the same problem today again, that mythtv sometimes just refuses to detect the cards, I deleted it. But I think (and hope) I found the real deal today, the problem, why mythtv sometimes just doesn’t detect the cards, although the kernel detects it correctly.

The solution is posted in another post here:

Howto: Use Floppy in Ubuntu

March 1, 2009 9 comments

By default, the use of floppy drives is disabled in Ubuntu 8.10.
The reason for a not responding floppy under /dev/fd0 (standard device) is the deactivated kernel module for floppies. To permanently activate the module loading of the floppy, simply run in xterm:

gksudo gedit /etc/modules

and add this simple line to /etc/modules at the end of the file


floppy

Don´t forget to save (and overwrite) the file afterwards !!!

The Floppy will be now available after reboot – to use it instantly, simply type into xterm:


sudo modprobe floppy

To mount the floppy, add a mountpoint in /media like

sudo mkdir /media/floppy

and mount it with:

sudo mount /dev/fd0 /media/floppy

To permanently have the device linked to the mountpoint, edit /etc/fstab:

gksudo gedit /etc/fstab

and add this line:

/dev/fd0 /media/floppy auto rw,user,noauto,exec,utf8 0 0

Again, don´t forget to save (and overwrite) the file!!!

Generate strong WPA2 passwords with Ubuntu

October 30, 2008 Leave a comment

To secure wpa/wpa2 keys from brute-force or dictionary-attacks, it is evident to use strong, that means long and purely randomly generated keys, which are in addition generated with a strong algorithm.

WPA/WPA2 limits the length of passwords to 63 digits, including upper/lowercase and special characters – so that’s what we are trying to generate….

Howto: Mythtv with acpi wakeup and mythwelcome

September 9, 2008 4 comments

UPDATE:Newer kernels (>2.6.22) handle wakeup alarms differently than in this howto, take a look at the official mythtv howto to cover newer kernels.

I am running an Epox 8rda+ (nforce2 chipset) with MythBuntu and will try to show, how to setup this mainboard with ACPI and mythwelcome, so that it starts with scheduled recordings and will shutdown automatically, when recording is finished.

Prequesites:
* A working mythbuntu installation with Backend and Frontend on the same machine
* Disabled acpi function in the BIOS
* BIOS runs in UTC
* Epox 8rda+ board (I can only somewhat guarantee the functionality of this howto with this mainboard ! )
* Mythbuntu latest (with fixes) – although this howto should work basically with other combinations too – but just basically
* use of /proc/acpi/alarm
* You simultanously look at the mythtv wiki
* You don’t expect this howto to be perfect or complete

How to convert a directory containing videos to .mp4 for mobile phones with one click

June 8, 2008 1 comment

Recently I described how to convert videos to .mp4 for your mobile phone using the avidemux2 gui.

But there is a faster, easier and more comfortable way to do this. With the following solution, you are able to convert a whole directory containing video files automatically to a phone-readable .mp4 format with just one click.

As in the previous Post, we still are using avidemux but now are invoking a job script to avidemux, so that we don’t need to configure the different settings manually. Along with a bash script, the conversion is done just with one double-click.
