Dell Latitude E6510, screen and touchpad

When we got our new laptops at work (Dell Latitude E6510) we had some various problems while installing our preferred Linux distros on it.

The first problem which we all had was trying to get the screen to work. I could get it to work by booting with the following kernel params xforcevesa nomodeset (I also removed the default quiet splash). Now I just run with only nomodeset, which works without problems for me, but without 3D. Jan has compiled a patched kernel for Ubuntu with 3D support but with less colors.

Then the second problem: scrolling with the touchpad didn't work. To fix this I ran the following commands:

1
2
3
4
56
7
8
9
10
cd /tmp/
wget http://launchpadlibrarian.net/57421117/patch-dell-e6510
sudo apt-get build-dep --no-install-recommends linux-image-$(uname -r)
apt-get source linux-image-$(uname -r)
cd linux-2.6.35/drivers/input/mouse/patch -p0 < /tmp/patch-dell-e6510 
make -C /lib/modules/`uname -r`/build M=`pwd` psmouse.ko
sudo rmmod psmouse
sudo cp psmouse.ko /lib/modules/`uname -r`/kernel/drivers/input/mouse/
sudo modprobe psmouse

Dear Author,

I am looking for a working patch or strings to patch manually for the 2.6.39 kernel (using 2.6.39-3) for patching with the older patch is not working fine. Tapping is still on and no vertical scrolling working.

Could you please help on this? I am happy about any hint in this direction.

Thank you and kind regards,
Tom

I'm currently running a default kernel and it seems to work without any problems so I think the patch is not needed anymore...

Hi and thank you,

which kernel you are running exactly?

I am running 2.6.35-23-generic with a patched selfmade psmouse module with vertical scrolling enabled and tapping disabled.
Since I experienced strange problems with performance with the latest 2.6.38-10-generic and dropped it again.

So I wonder the following...

When I run the 2.6.35-23-generic with the self maden psmouse module and I go and compile the latest 2.6.39-3 then tapping is enabled but vertical scrolling does not work.

Does it mean the patch is still needed in the new kernel as well?

Kind regards,
Tom.

I managed to make it work the same way with 3.0.0-rc6, but using the "patched patch" described here.

Hi,

does the second workaround also fix the disable tap on writing with alps on "Dell/E5420" with "ImPS/2 ALPS GlidePoint" ?
I have a problem that on writing the cursor all the time jumps to the mouse pointer. This is really disturbing behavior. Someone a clue?

Cheers!

Hey Gunnar,

That is another problem AFAIK. The problem seems to be that the touchpad is not correctly recognized as a real touchpad. A driver is currently being developed but it still has some problems when I tested it.
I believe I found that info here: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/550625

Hi Jeroen,

While the touchpad works initially, it gets worse and worse as time goes on for me and my E6410. I find that loading psmouse with the proto=imps makes the touchpad work well for pointing, but scrolling is disabled. See my bug report here.

What psmouse are you using now?

Thanks,

Rob
