Touchpad Tap and Login Screen Issue

Postby samriggs on Thu May 12, 2011 11:34 am

Howdy all

Just installed LMDE and am loving it. I switched from mint 10 mainly because I got tired of reinstalls.
Thanks to forum here it all went pretty smoothly (especially updating the grub after over 800MB of updates that took over 2 hours :lol: )
Just have 2 issues so far, the tap on the touchpad was not set by default, which was no problem, I went in and activated it, but it is still not activated on the login screen, which is really not a big deal, just thought it might be nice to finish off the whole thing with the last two bugs.

Anyone know how to activate the touchpad tap on the login screen?

Bug number two I found and been searching (maybe not good enough, I don't know) is the bug of the login screen in the administration, you cannot get into it at all, when you click to unlock it, nothing happens at all.

Is there a fix for the unlock bug in the login screen yet?

That's the only two things I had an issue with so far, other then this it's all good and am loving it.

Thanks in advance for any help anyone can provide.

I just switched to Mint LMDE 64 after several years of using Ubuntu. I am seeing these two issues as well. I thought it was a driver issue with the Synaptics trackpad on my HP dm4 laptop. Now I know I'm not alone.

In addition, right-click doesn't work. I tried several trackpad utilities with no luck. I finally got around the right-click issue by enabling the accessibility options and enabling the option to "Trigger secondary click by holding down the primary button."

Touchpad
To activate "click on tap" for your touchpad, type sudo gedit /usr/share/X11/xorg.conf.d/50-synaptics.conf and replace the content of the file with the following:

Section "InputClass"
Identifier "touchpad catchall"
Driver "synaptics"
MatchIsTouchpad "on"
Option "TapButton1" "1"
Option "VertEdgeScroll" "1"
EndSection

:mrgreen: Cool that fixed it.
Thanks a bunch.
The tap not working on the loading screen wasn't a really big deal for me, I just used the left clicker instead, but it works now after that fix. Should of looked for that more, I usually find these fixes by digging through enough pages on the web.
Again I thank you again.
Now if I can get the login screen authentication button to actually pop up and let me put in my password so I can use that part in the admin section that would be priceless :D
Hopefully that fix will happen soon, I understand Clem is probably getting no sleep right about now getting version 11 ready, I have 4 computers waiting for that update :lol:
This is mine though which I'll keep LMDE on instead.

I thank you again.

I finally found a solution for the right click on my HP Pavillion dm4. I found that using the accessibility option caused "AT SPI Registry" to run, interfering with shutdown. I used this post on the Ubuntu forums (http://ubuntuforums.org/showthread.php? ... pad&page=6) and the post from aljoriz, above, to finally end up with a /usr/share/X11/xorg.conf.d/50-synaptics.conf file that looks like this:
Code: Select all
Section "InputClass"
   Identifier "touchpad catchall"
   Driver "synaptics"
   MatchIsTouchpad "on"
   Option "TapButton1" "1"
   Option "VertEdgeScroll" "1"
   Option "EmulateTwoFingerMinZ"  "29"
   Option "EmulateTwoFingerMinW"  "5"
EndSection


Now I can tap two fingers on the trackpad as my right-click. These are the magic two lines that make it work:
Option "EmulateTwoFingerMinZ" "29"
Option "EmulateTwoFingerMinW" "5

Note: I also discovered that on the dm4 keyboard, there is a menu button between the <alt> and <ctrl> keys to the right of the spacebar. It *almost* works as a right-click because it emulates <Shift>+<F10>. It doesn't work properly in Firefox, though, since it produces the equivalent of a right-click on the whole web page, rather than a right-click on a link on the page. The two-finger-tap DOES work properly -- exactly like a hardware right-click button.
