This is reasonably smooth, but you can get into various
Also note that if you are running a custom user python
(e.g. if you load up a virtualenv or anaconda python in your
.bashrc) then this will not work, since
openrazer inspects your path to find its python.
UPDATE: for some reason this doesn’t work on Ubuntu 19.10 for me. However the competing GUI RazerGenie works fine.
Anyway, after all that fussing, you now have a rainbow-coloured GUI to control your rainbow-coloured keyboard lights! Wheeeee!
Two finger right click
Horizontal scrolling backwards
It is for me. Per default, vertical scrolling is “natural” and horizontal is “traditional”. Cognitive dissonance.
xinput --list # look for a "Synaptics" pointer xinput --watch-props <id>
finds and dumps info about the erroneous thingy which for me is a
Synaptics TM2438-005 at
xinput --set-prop <id> "Synaptics Scrolling Distance" -94 -94
It turns out there is a special synaptics command synclient, which also does it.
sudo apt install xserver-xorg-input-synaptics
AFAICT this is deprecated because it doesn’t use the modern libinput although they seem to coexist peacefully on my system so maybe I should not care about that until something breaks nastily.
synclient on recent ubuntu seems to cause the backwards horizontal bug.
No longer recommended.
The archlinux backgrounder might make it clear if I were inclined to read it.
synclient VertScrollDelta=-94 HorizScrollDelta=-94
This needs to be run after laptop resume also
which gets complicated.
I needed to set up a script that will talk to X,
#!/bin/bash #title :scrollrite.sh #notes :Script gets called from /lib/systemd/system-sleep #========================================================================== sleep 5 declare -x DISPLAY=":0.0" declare -x XAUTHORITY="/home/me/.Xauthority" synclient VertScrollDelta=-94 HorizScrollDelta=-94
Then I need to invoke it after waking.
UPDATE: This after-sleep thing seemed to work for me but as of now, does not. Since the whole problem was transient perhaps I was only imagining it
UPDATE UPDATE: On ubuntu ≥ 19.10 the entire problem seems to have sublimated away and scrolling is consistent.
Power management and suspend/hibernate
Fails to sleep when lid closed
Things seem to go weird for me, especially with
nvidia drivers which apparently is common.
The problem looks like this
Freezing of tasks failed after 20.00 seconds (21 tasks refusing to freeze, wq_busy=21): ...<nvidia related stacktrace>
Keeps on sleeping after suspend
After the laptop has gone to sleep one time it has narcolepsy and keeps sleeping again?
I found this fix somewhere: append
button.lid_init_state=open to the value of
My screen never powers off even when laptop is idle
Weird, mine too.
But no longer.
I fixed it using
xset dpms 0 0 600
See the Ubuntu compatibility page.
Notably webcam is broken, and fan control is
weird and sounds like a jet aircraft
sound only intermittently like a jet aircraft in the latest update.
Perhaps fancontrol could help?
The archlinux page
has some suggestions for the webcam thing. Specifically, put
options uvcvideo quirks=512
That does not fix it for me.
NVMe drive not detected
Maybe also use nvme-cli to check drive health.
Make the fix permanent with
to the kernel string. doesn’t seem necessary with kernels >4.10.
See the ubuntu resize instructions.
