Hi everybody,
I gotta say I'm kinda of a newbie here, so please don't kill me!
I'm an openSUSE TW user and I got an issue which is last too long now and I can't figured out how to fix it. Tried to ask in plenty other places, but I couldn't solve much. to Hope you can help.
Long story short, I had an nvidia GT710 which was way enough for my use (music production and some retrogaming). I always hated how the proprietary drivers works on Linux and I recently discovered I could use my igpu (HD530) to perform even better than the GT710 and without the boringness to have proprietary drivers running on my machine.
I simply set up my BIOS, switched my HDMI cable from my nvidia to the hd530 and it worked straight away. Everything beautiful, animation and transparency were better and everything was great, except the machine won't poweroff or restart at all anymore. I had to do it brutally every single time.
However If I use "nomodeset i915.modeset=0" into the grub, it does start, no problem with restarting or poweroff anymore, but there is not 3d acceleration hardware (so no transparency, nice effects, animation, etc anymore). My igpu is kind of castrated.
I tried to switch the HDMI back to the Nvidia and everything goes back to normal.
That's all.
I really would like to use my Intel which apparently perform better.
Any idea how to fix it?
Thank you so much.

Not sure of you tried this already, but open 3 terminal windows:
In one "tail -f /var/log/messages"
In second window "dmesg -wHT"
In third terminal window "shutdown -r now"

Do you see any thing in dmesg or log entries in messages that could indicate what's happening?

More background on OP's situation. I thought all OP's problems were solved except for one: OP seemed to be persuaded he should use the NVidia GPU for "offloading" instead of simply removing the NVidia card and using the IGP.

• nomodeset is primarily a troubleshooting parameter. It blocks from optimal operation all types of GPUs, APUs & IGPs, by preventing use of competent FOSS X drivers.
• i915.modeset=0 is primarily a troubleshooting parameter. It blocks from optimal operation only Intel IGPs, by preventing use of competent FOSS X drivers.

Using both nomodeset and i915.modeset=0 is redundant. Using either will cause either failure of X to run at all, or will cause fallback to one of two crude, low performance, generic X drivers that do not provide acceleration or support most widescreen modes.

Thus, most people cannot be happy with GPU performance when nomodeset or i915.modeset=0 are employed, because in most cases using either will prevent using a display's native (optimal) resolution, and will operate sluggishly. The primary exception to this is when any of NVidia's proprietary graphics drivers are employed.

Hi,
Thank you for your response.
I tried "tail -f /var/log/messages" but it says "tail: cannot open '/var/log/messages' for reading: No such file or directory"
The others two commands are giving me this:


The system stuckes there. I have to shutdown manually.

Thank you for adding these info
