Touchpad or mouse not working after ubuntu update from 12.04

I update Linux ubuntu from 12.04 via command line. After end of update I get message update complete 3 packages have error. One of them is ubuntu – desktop. I reboot pc. After reboot trackpad does not work. When I connect mouse with usb also does not work. I think issue is some packages have not installed/updated properly. What I have tried in recovery mode and alt + ctrl + f2:

sudo apt-get install xserver-xorg-input-synaptics
Result: package already newest version.

Sudo apt-get upgrade
Result: 0 upgraded 0 to remove and 246 not upgraded.

Sudo apt-get update
Result: failed to fetch on many lines. I think it’s networking problem.

Sudo apt-get dist-upgrade

many lines ‘failed to fetch’ ‘e: unable to fetch some archives’ I think nothing is installed on this step cuz it ends in 2 seconds.

Please help me I have very dear files to me on this computer that I don’t want to lose 🙁

Non-working SYNA3602 touchpad on Xubuntu 19.04

I have a non-working SYNA3602 touchpad on a Trekstor Prime book C11B notebook. I am on Xubuntu 19.04.

There are a few threads on problems with this touchpad on different forums (most threads from 2018) and a patch available under the following link:

Though, the patch should be included in the mainline Kernel since Linux v4.19 and I have tried different Kernels from 5.0 upwards. Currently I am running 5.2.0-050200-generic.

dmesg | grep -i i2c-syna gives me the follwing output: Code: [ 3.039251] i2c_hid i2c-SYNA3602:00: i2c-SYNA3602:00 supply vdd not found, using dummy regulator [ 3.039281] i2c_hid i2c-SYNA3602:00: i2c-SYNA3602:00 supply vddl not found, using dummy regulator [ 3.045751] i2c_hid i2c-SYNA3602:00: unexpected HID descriptor bcdVersion (0x00ff) Is anybody able to help me ?

Thank you in advance! ea

Previously functioning touchpad disappears from /proc/bus/input/devices — now what?

While copying files to a usb-drive using nautilus, the nautilus windows hanged. After killing any relevant processes and rebooting, my touchpad no longer works! Worse than that it doesn’t even show up when I

cat /proc/bus/input/devices

Here is a link to the output of that command.

Any advice on how to track this problem down would be much appreciated. Everything I have found online starts with “first find your device in /proc/bus/input/devices, then….” but the advice about what to do when it doesn’t show up there doesn’t seem to apply in my case—e.g. they say it might be an issue where the kernel doesn’t recognise my hardware, but my kernel hasn’t changed.

Nothing obvious is sticking out when I grep my /var/log directory for ‘synaptic’ or ‘touch’. Any advice would be much appreciated!

The laptop is an HP Envy Notebook 13-ad134tx

touchpad doesnt work :( exceptional problem

maybe someone will inspire? 🙂 Well, we have a small problem – the patient is akoya (touch screen). Of course, Linux is necessary for work – here, unfortunately, there is a problem. Due to the fact that the screen is touch, linux classifies this screen as a touchpad (the touchpad does not work). We’ve tried many ways, but it can’t be bypassed for now – it’s still the touch screen that plays the role of the touchpad. Has anyone encountered a similar problem? I greet and have a nice evening

Laptop keyboard & touchpad not working properly when mouse plugged in

I have a ubuntu laptop from the brand Tuxedo. When I plug an external mouse in (which works fine on my Windows pc), I can only click into one window – on the mouse, but also the touchpad. Plus the keyboard won’t work properly any either. This happens in such random ways that I can’t really describe any more precisely. When I pull out the mouse usb cable, everything is fine again.

Stopping touchpad clicks registering as right-clicks when there’s another finger already on the pad

Often I will drag the cursor to a particular location with my right finger and then press the touchpad with my left finger to left-click, whilst my right finger is still on the pad. This works in Windows and other laptops I’ve used before, but in Ubuntu 18.04 these keep registering as right-clicks whenever my fingers are too close together. This makes clicking and dragging particularly annoying as I have to lift my other finger off the pad before initiating the click.

Basically I want to configure my touchpad to ignore the presence of a second finger when it is clicked, and just do a left click regardless, but can’t spot a relevant setting in xinput --list-props

Lubuntu 18.04LTS touchpad config: CLI solution to turn off tapping?

I have seen numerous posts about touchpad issues, but have mainly seen GUI solutions, such as adding “touchpad-indicator” (which didn’t work the way I’d hoped) or synaptics (which froze my keyboard at login requiring a whole reinstall). I have seen a great tutorial of exactly what I hope to accomplish for 18.10 here: anglehit

But the problem is I don’t seem to have an xorg.conf.d file in /etc/X11 in Lubuntu 18.04LTS.

I would love to just open a text editor, change a setting to something like:

tapping = "off" 

Hit save, and be done. Is there any way to do this on Lubuntu 18.04LTS?

Thank you very much.

How to correct mapping of Touchpad and 2nd Mouse device on Xfce?

My Synaptics touchpad is device number 7 and the left clik works on the xfce desktop but not on windows or the menu bar. Same goes for the external usb mouse, which is number 5. Device number 6 are two other mouse buttons present on the laptop (HP Elitebook 2540p). After boot everything works fine until I hit one of these laptop buttons then the mentioned behaviour above happens. I now want to disable the devices one by one to check which is triggering the error. I also tried evtest and every button works fine (left, right). So there is some mapping chaos in X happening.
