Blank window when running Quartus Prime Lite in sudo mode Ubuntu 18

[MAlek2]

Hello. When i'm running Quartus Prime Lite in sudo mode i see nothing but blank screen.

I'm running Quartus with sudo because without it Quartus stucks when generates any IP.

I tried 17.1 and 18.1 Quartus versions with the same result. I didn't have that problem on Ubuntu 16.

I will try it on my side and let u know the result soon

Hi, Can you make sure all the library below had been installed in your Ubuntu? libc6:i386, libncurses5:i386, libxtst6:i386, libxft2:i386, libc6:i386, libncurses5:i386, libstdc++6:i386, libc6-dev-i386 libxft2, lib32z1, lib32ncurses5, lib32bz2-1.0, libpng12 Extra for ubuntu 18.04: libqt5xml5, liblzma-dev Also extra for ubuntu 18, libpng12 is no longer available via the apt-get method, download and install libpng12 from here: https://packages.ubuntu.com/xenial/amd64/libpng12-0/download

I checked all libraries and it is all good. I actually can run Quartus normally. But with sudo i got this problems. Maybe there is something wrong with environmental variables?

[Kenny_Tan]

Yes.. seems like I was able to see the same.. will get back to you on this.. also, can you just use it normally?

[MAlek2]

Yes. I can run it normally but it stuck when generates IP instances

[Kenny_Tan]

Can u check on your environment variable before and after su command? Perhaps after the su command, there are some environment change. I will check on my side as well. I will check again whenever the IP instances created , it got stuck or not.

[Kenny_Tan]

Not sure if you have check it?

[MAlek2]

I've checked environment variables and they are different. Also in normal mode i have much more variables than under sudo. I tried to copy some of them but with no success.

[Kenny_Tan]

Can you copy all of them? send us a screenshot of both of your environment variable.

[Kenny_Tan]

Try not using sudo. The IP generation success on my side. check again your lib https://www.intel.com/content/www/us/en/programmable/support/support-resources/knowledge-base/tools/2019/why-does-my-quartus-prime-18-1-fail-to-run-on-ubuntu-18-04-lts-.html?wapkw=why+does+my+quartus+prime+18.1+fail+to+run+on+ubuntu+18.04+lts%3f

[MAlek2]

This doesn't work for me, unfortunately. My Quartus stucks at any try to edit or create PLL, FIFO, etc. Running without sudo is not an option.

[MAlek2]

Previously you typed that you was able to see the same thing. How did you resolve it?

[Kenny_Tan · Accepted solution]

as mention, from my side, I just dont use the su. I also face stuck issue when try to edit the megawizard. It was resolve by https://www.intel.com/content/www/us/en/programmable/support/support-resources/knowledge-base/tools/2018/why-does-the-megawizard-got-hang-.html

Make sure the below to avoid the IP stuck.

1.Install Java from Oracle. Java version after install is:

java version "1.8.0_121"

Java(TM) SE Runtime Environment (build 1.8.0_121-b13)

Java HotSpot(TM) 64-Bit Server VM (build 25.121-b13, mixed mode)

2. Try to install Quartus in a directory path that has no uppercase letters.

3. Right after Megawizard is opened, stretch the window out a little (drag a corner) and make it so scrolling is not necessary.

4. make sure when you launch quartus, there are no error message showing lib is missing.
