ALPS Touchpad Scrolling support

Since I loose vertical scrolling support, every time I update the kernel and have to patch it again, I write a small "How-To".

This is for my Dell Latitude E5410 ALPS Touchpad, which have a lot of problem, not only on Dells. Simply because ALPS is very, very closed regarding open drivers or specifications (what makes no commercial sense, since they earn money with selling hardware, not with selling drivers for it).

This experience, however, forces me to not buy any Laptop with ALPS hardware anymore in the future. If you are a linux user and want to buy a new Laptop, ask your hardware vendor what Touchpad is used in your laptop. Do NOT buy machines with ALPS hardware or you will get problems with it.

This How-To is for ubuntu maverick (10.10) 32bit and the generic 2.6.35 Kernel. If you want to patch other kernels you have to search or the appropriate patch, compiled against your kernel, in the bugreport or patch and compile the psmouse.ko module by yourself.


Now to the task:

Backup the original psmouse module. You might end up with no mouse support at all after patching and want to undo the changes.

sudo cp /lib/modules/`uname -r`/kernel/drivers/input/mouse/psmouse.ko /lib/modules/`uname -r`/kernel/drivers/input/mouse/psmouse.ko.backup

Now download the psmouse.ko module from https://bugs.launchpad.net/ubuntu/+source/linux/+bug/550625/comments/194. The patch disables clicks when tabbing on the touchpad (this feature is annoying if you are writing text directly on the laptop and your arm accidentally tabs the touchpad) and enables vertical scrolling on 2.6.35 gerneric 32bit Kernels.
If you want to patch other kernels you have to search for the appropriate patch in the bugreport or patch and compile the psmouse.ko module by yourself.

If you have your correct psmouse.ko fi

wireless keyboard mm keys mouse issues

I recently bought a Microsoft Arc keyboard to work with my ubuntu 10.10 maverick system and I am very happy with it.

Only one problem occured: When I hit one of the multimedia keys on it (Volume up, down or mute) my left mouse button stopped working. It seems like pressing a multimedia key is forcing a pushed down left mousebutton until you restart the x-server.

Really annoying, but the ubuntu guys have a fix for ubuntu maverick 10.10 in launchpads bugtracker already.

Install this Package for 32bit systems or this one for 64bit systems and reboot your system.

The annoying keyboard/mouse issue is gone.


Should work for ubuntu lucid 10.04 and other keyboards with multimedia Keys (Microsoft, HP, A4Tech) which suffer from this issue, too.

change nautilus side pane colour

[UPDATE 18.01.2011]
Finally somebody had the same problem like me and came up with a better solution. The problem with what I wrote: Changes get lost on nautilus updates.

To get the "real deal", stick to Joeys How-To at OMG! ubuntu. Thanks for reading.


to change the side pane colour in nautilus, open the gtkrc file for your theme


sudo gedit /usr/share/Ambiance/gtk-2.0/gtkrc

and add

style "treeview-mod"
    GtkTreeView::even_row_color   = "#F2F1F0"
widget "*NautilusNavigationWindow*" style "treeview-mod"

only issue: when switching the view to treeview, the background changes, too. But thats not so bad as you mostly use treeview when the folder is full, so that you never see the background in treeview anyway.

I did this with nautilus elementary mod, so I do not know if it fully works with the standard nautilus. 

Take a look at these threads at ubuntuforums to get your own clues:

have fun customizing your nautilus. If not, just stick to the standard themes. ;)

Dell Latitude E5400 to E6500 Microphone issue

My integrated microphone did not work after installing ubuntu maverick 10.10. What a shame. I found a quick and easy solution though.

This article is a completely copied post from lidex, a user at the ubuntuforums. The Original Post can be found here.

This solution should work for integrated microphone issues with Dell Latitude E5410, E5510, E6410 and E6510.

Register with the ubuntuforums and thank lidex for this, I just found, copy and paste this:

Using a Terminal="Applications->Accessories->Terminal"
Open this file for editing:
 gksudo gedit /etc/modprobe.d/alsa-base.conf
Insert this line at the bottom:
 options snd-hda-intel model=dell-s14
Save. Close. Reboot. Check your levels in alsamixer.
Press <F6> to select the correct soundcard.
Press <F3> to show playback levels. <F4> selects capture levels [or use <Tab>]
Use the left/right arrow keys to select and up/down arrow keys to change levels. <M> to mute/unmute.
Go to "System ->Preferences ->Sound" and make sure the correct soundcard is default and adjust your profile on the hardware tab.

Now if that doesn't work, upgrade your alsa install using the alsa-upgrade link in my sig.
