Two remarks: is your license file expired? Just request a new license and try again probably copy/paste error but at the end of your line the 't' is missing in --64bit Re: Quartus Prime Lite 21.1 on Ubuntu 21.10 Questa does not start Solved by editing the desktop file: Edit /home/bert/Desktop/Quartus (Quartus Prime 21.1) Lite Edition.desktop Exec=env LM_LICENSE_FILE=/home/bert/1-V4I9CH_License.dat /home/bert/intelFPGA_lite/21.1/quartus/bin/quartus --64bit Quartus Prime Lite 21.1 on Ubuntu 21.10 Questa does not start My laptop is running Ubuntu 21.10. I just installed Quartus Prime Lite 21.1 which no longer includes ModelSim Starter Edition but Questa Intel FPGA Starter Edition instead. According to https://www.intel.com/content/www/us/en/programmable/support/support-resources/download/os-support.html Ubuntu is not supported to run Questa. Is this really true? I created a free license on the Self Service Licensing Center and entered the location of the license file in Quartus Prime Lite Options as well as the path /home/bert/intelFPGA_lite/21.1/questa_fse/bin in General/EDA Tool Options. When I try to start in Tools/Run Simulation Tool/Gate Level Simulation I get Info (22036): Successfully launched NativeLink simulation (quartus_sh -t "/home/bert/intelFPGA_lite/21.1/quartus/common/tcl/internal/nativelink/qnativesim.tcl" "Lab05" "Lab05") Info (22036): For messages from NativeLink execution see the NativeLink log file /home/bert/FPGA/Labs_Companion/Lab05/Lab05_nativelink_simulation.rpt But nothing happens. Are there libraries that I should still install in Ubuntu to be able to run Questa? SolvedRe: Quartus Prime 20.1 Lite on Ubuntu Linux on laptop with 4K screen Thank you very much for this link. I could indeed modify the file .modelsim in my home directory where I made all fonts in "PrefDefault" size 26 instead of 12. Then Modelsim is manageable. Although the icons are still too small and the pop-up windows like File/Open are hardly readable and way too small. But it is workable. Quartus Prime 20.1 Lite on Ubuntu Linux on laptop with 4K screen I have a laptop with a 4K screen that I use in 3840x2160 resolution running Ubuntu Linux 20.10. I installed Quartus Prime 20.1 Lite. Quartus is usable in this mode but Modelsim is not. I need to switch to 1920x1080 resolution to use Modelsim. Is there a workaround to work in 4K? Solved
