Few things, although I cannot confirm anything because I don't run CM.
1) Do you have any SU issues with any other app?
2) It is possible that you might have 'accidentally' denied SU in no frillz. Maybe try to clear data and cache of the app and try again. Or possibly re-install.
3) Have you tried Trickstermod? IMHO it is the de facto free kernel app, of which you can do much more with the Grimlock kernel
4) Try one of the 5.1 kernels I just updated? I haven't tried them on CM but I would think that they will work ok.
Hey
@JuraP. Thanks for your support and reminding me to upload the new 5.1 versions LOL! They are up now in the downloads section, and thanks to
@lj50036 for the help in getting these ready. You are a true monster!
Firstly, the lite version clocks up to 1.7ghz compared to the "performance" version which only clocks 100mhz higher to 1.8. The biggest difference between the two is that in order to get that extra bump in clock speed, we had to do some very aggressive changes to the voltage table and GPU, which was likely what causes the glitchyness on your keyboard.
Secondly, wait..... there is no secondly.... I'll just stop talking now
