Using this boot workaround, I have been able to install Ubuntu 19.04 on my recently acquired ASUS UX533FN:
- ASUS BIOS version 202 (already up-to-date)
- NVidia GeForce MX150 with NVidia proprietary driver 418 installed
- Linux version 5.0.0-16-generic
- no Intel microcode update for the moment (
dis_ucode_ldras linux boot param)
Audio is working! For comparison, I haven't been able to have it working on Ubuntu 18.04 LTS.
Now my problem is the CPU temperature is very high! around 70-80°C without doing anything special that'd claim much CPU power – just writing these lines for example… and the fan doesn't run at all.
I have found the following workaround:
sudo prime-select query
If this command returns
nvidia, then run:
sudo prime-select intel
then log off.
When you log back on, check the CPU temperature decreases and reach reasonable values (between 40°C and 50°C for example, depending on the room temperature), and you should hear the fan running when needed.
But this is only a workaround with which the NVIDIA GPU is not used at all…
How can I have the NVIDIA graphics card and the fan operational, without the CPU temperature going high?
Maybe I should stick with the Intel graphics only? I didn't ask for an NVidia card in the first place… I didn't realize this laptop had an NVidia card when I bought it.
