Blank window when running Quartus Prime Lite in sudo mode Ubuntu 18 - Blank window when running Quartus Prime Lite in sudo mode Ubuntu 18 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. Replies: Re: Blank window when running Quartus Prime Lite in sudo mode Ubuntu 18 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. Replies: Re: Blank window when running Quartus Prime Lite in sudo mode Ubuntu 18 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 Replies: Re: Blank window when running Quartus Prime Lite in sudo mode Ubuntu 18 Previously you typed that you was able to see the same thing. How did you resolve it? Replies: Re: Blank window when running Quartus Prime Lite in sudo mode Ubuntu 18 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. Replies: Re: Blank window when running Quartus Prime Lite in sudo mode Ubuntu 18 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 Replies: Re: Blank window when running Quartus Prime Lite in sudo mode Ubuntu 18 Can you copy all of them? send us a screenshot of both of your environment variable. Replies: Re: Blank window when running Quartus Prime Lite in sudo mode Ubuntu 18 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. Replies: Re: Blank window when running Quartus Prime Lite in sudo mode Ubuntu 18 Not sure if you have check it? Replies: Re: Blank window when running Quartus Prime Lite in sudo mode Ubuntu 18 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. Replies: Re: Blank window when running Quartus Prime Lite in sudo mode Ubuntu 18 Yes. I can run it normally but it stuck when generates IP instances Replies: Re: Blank window when running Quartus Prime Lite in sudo mode Ubuntu 18 Yes.. seems like I was able to see the same.. will get back to you on this.. also, can you just use it normally? Replies: Re: Blank window when running Quartus Prime Lite in sudo mode Ubuntu 18 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?
