Screen flickering - kernel panic - uncontrollable touchscreen - tiny letters

HI,

First off... thank you for providing this support forum. I know the hardware seems to clash a bit with linux, I hope we can provide a working system very soon. 

I normally use OpenSuse, been super happy with it for over 10 years. Unfortunately, I couldn't get it to work as I wanted, the touchpad was pretty terrible, so many repeated keystrokes... that I opted to install kubuntu 15.04, to get more support. 

I keep having some issues, I thought it would be useful to tell them here: 

- I work with an external screen in the office and on laptop at home. The laptop letters are TINY due to the excellent resolution. So I change the dpi settings to make things readable. So in the morning when I connect my external screen, things are HUGE. Because, as everybody, I'm lazy, I just constantly "zoom" scroll my browser... it's not the nicest experience. But ok... that's not my main concern. 

- After opening certain software: synaptics center, installing tlp, musescore,... my screen starts to flicker uncontrollably. The mouse cursor doesn't work at all anymore too. This usually ends with a kernel panic (blinking caps lock). I have to reboot a few times before this goes away and I usually also type this: 

sudo apt-add-repository ppa:canonical-hwe-team/sputnik-kernel
sudo apt-get update
sudo apt-get install linux

(is this the right command btw to activate the latest sputnik kernel? How do I make this stick?)


- Battery life: I usually get 3-4 hours with a dimmed screen. (??)

- a few times, after closing the lid of my laptop, the processor got locked into max mode. I didn't notice and put the laptop in my bag. After 2 hours it was so hot I couldn't touch it anymore. Scary!



Positively: my mic works fine (which is great, because I am a music technology researcher and I skype all the time).


Is there anything that will make my life easier?
