Numerical pad against my consent Print
Sunday, 17 August 2008

One of the typical things of a laptop keyboard is that it's too small to also contain a numerical pad area on the utter right of the keyboard (Except for some 17inch laptops). To cope with this loss, most manufacturers project the numerical keypad on some other keys. By having some kind of "modifier" key, there can be switched between normal alphabetical character or the values and symbols of the numerical pad.

Unfortunately, something is wrong with either Ubuntu, Gnome or the Asus C90s: once in a while it enables the numerical pad. It could also be that I myself press sometimes a secret keyboard combination that I did not discover yet. Nevertheless, it causes me to have the numerical pad enabled against my will. Although uglier things happen with people against their will, it would not be as bad if you knew how the reset the keyboard. And as I'm not a bookkeeper and never will enable this feature-for-some for myself, I have no way to disable it.

It happened to me some time before also and after a while I remembered that I found out that the problem only occurred during gnome, and the gnome session of my own user in particular. So knowing this, it was pretty easy to solve it: remove all your .gnome-related directories in your home directory.

As I did not want to reconfigure my gnome desktop again, I decided to do some research to see where the wrong setting came from. Well, it was:

 .gconf/desktop/gnome/peripherals/keyboard


This entry contained a host-(hostname) entry and that contained directory called '0' (zero). Here a %gconf file was standing that contained the following line:

<gconf>

        <entry name="numlock_on" mtime="1218998942" type="bool" value="true">

        </entry>

</gconf>



Removing the keyboard directory altogether (as I did not have any special keyboard things installed) solved my problem. Or will there be an easier way to solve this?

Turning wireless on in Ubuntu Print
Thursday, 17 July 2008

During installation of the ndiswrapper (note; 32-bit only!),I found the following:

Sometimes, wireless is disabled during start, so trying wifi will not work.

To enable the wirelessdo the following as root (sudo su -):

. /usr/share/acpi-support/state-funcs
setLEDAsusWireless 1 

This saves a lot of time figuring out why you cannot get wireless to work under (Ubuntu) linux...

Webcam not supported in linux Print
Thursday, 13 March 2008

The build-in webcam (the 270 degrees turnable on top of the LCD) is not (yet) supported under linux. It seems to run on the GL860 chipset, not to be mistaken for the GL860A (which is supported). The GL860 has not yet linux drivers.

 lsusb shows the following line for this device:

 Bus 001 Device 003: ID 05e3:0503 Genesys Logic, Inc.

See the following links for more details:

Ubuntu start-up framebuffer Print
Wednesday, 05 December 2007

There is a problem with running Ubuntu on the Asus C90S: as it has a resolution of 1680x1050, during or just after installation, something goes wrong with the bootsplash or framebuffer display. The Asus has a Nvidia 8600 GT (for the record...)

 The result is that you have to wait until X comes up with the login screen. So you don't see intermediate results. Another problem is that the console windows under Alt-F1 until Alt-F6 will not display. (You can circumvent the latter part by doing a sudo modprobe vesafb)

 I've tried many things, but this list gives an idea what to change to get it to work:

  1. Make sure /etc/usplash.conf is the same as the resolution you try to display at start.
  2. Make sure your vga=XXX is equal to the value for the resolution (make sure it's the same as in the previous step)
  3. Make sure /etc/modules.conf contains vesafb
  4. Make sure /etc/initramfs-tools/modules contain fbcon and vesafb
  5. Do a sudo update-initamfs -u
  6. I also did a depmod -a but I don't think this is really needed.

Windows Easy Transfer not so easy Print
Wednesday, 28 November 2007

ImageAs a small side-step to my previous Windows Vista experience I had a small job to do: I had to convert data and settings from an older PC running Windows XP to a new one running Windows Vista.

I actually found a tool to convert all data on the XP (in Dutch: bestanden en instelling overzetten wizard, or in English something like files and settings transfer wizard). Unfortunately, the new Vista PC did not have this wizard, but did have the windows easy transfer wizard. Of course, if it looks the same, smells the same, in windows it probably is NOT the same. And this is true, as this is probably a new or updated program that was not available in XP. Fortunately you can install it on XP and proceed.

So, happy me, I checked everything: convert all accounts and all settings and go! A smart solution where a small string is printed on one machine is used to make sure these two computers participate together in a easy transfer.

Because it was quite some GBytes and the older computer only had a 100Mbit network card, it took -quite- long. No worry, keep the machines running for the night and easy does it !  But in Windows world again, it is NOT. It gave an error access denied on the XP machine, just at the point you expect it to say "I'm finished". No other information so you don't know where it did not have access to. But the account that ran the wizard ran on Administrator permissions, so how could it not have access? (before this, it already stopped about 5 times to tell me it could not transfer some file in the middle of the transfer process, eager to tell me before continuing with all other files)

So I tried again, and failed: access denied. I selected a lot less settings using the Advanced option, and access denied again. Maybe the user was accessing something, had a file open so it could not access it? No worry, just start your XP in safe mode with networking support, so it will not run unnecessary processes and start the wizard, smart? Yes, that will work! Anywhere but NOT in windowsland: you could not run the wizard in safe mode (why not? please tell me why not!). So I made an extra user with administrator rights, ran the wizard again: access denied.

To end this story, I only selected the bare minimum that I needed: Outlook e-mail settings, the printer settings and nothing more. I hear you say: no, that will not work, give it up! But, no, give this company some credit: it worked! It finally managed to convert the e-mail settings. Only for some reason, my printer settings were not converted. Bad, but not really a disaster as I could just download and install the latest drivers as an alternative. 

For the rest of the conversion I did it the usual way by just sharing some folders and copying them over the network.

This was definitely my last voluntary Windows job for me.  Ubuntu will prevail.
