I have been working on Jetson TX2. I know there is openCV for python2 but I was trying to install opencv 4.0.0 for python3. The build folder was large and during the make, it said the disk place is full and killed the progress. Then I can’t open the file browser. I delete some files to free up so…

“sha1sum” is standard content and is always installed. If you don’t see it with “ls /usr/bin/sha1sum”, then part of your file system is missing. How that would go missing I don’t know, but it does imply important parts of the system may be missing (including those for the GUI).

Hi jchen446, As you mentioned - “it said the disk place is full and killed the progress.”, that’s the possible cause due to it was normal before. Thanks.

Hi friends, The total disk space is 28G. I have already free up 10G and there is now 12G left(55% used). But still after I reboot the GUI doesn’t shows up and got into text mode. Any suggestions about how to check what’s wrong? Thank you

Since you can get to a console, then after boot save a copy of “/var/log/Xorg.0.log” and post it here (you might need to rename it with a “.txt” suffix). If you hover your mouse over the quote icon in the upper right corner other icons will show up…the paper clip icon allows attaching to an existing…

I’ll paste it now. Please check. Thank you. Since it keeps scanning… I’ll also paste the content here. [ 10.278] X.Org X Server 1.18.4 Release Date: 2016-07-19 [ 10.278] X Protocol Version 11, Revision 0 [ 10.278] Build Operating System: Linux 4.4.0-97-generic aarch64 Ubuntu [ 1…

Some interesting log lines (and this is after you’ve cleared up some disk space): [ 10.302] (WW) NVIDIA(0): Unable to get display device for DPI computation.

Why it picked 640x480? Is some files not detected forced it to? I changes to another display screen and it still shows the text mode. The log after adding the ModeDebug is pasted. BTW when the system is starting(or rebooting) some failure showed up. [FAILED]Failed to start dnsmasq - A lightweigh…

FYI, 640x480 is because no monitor specs were detected and the driver picked a basic mode which many monitors support (but yours does not). The specs are not in a file (they were back in the days of 15-pin VGA cables)…they are in the monitor itself and are sent via the “DDC” wire in the HDMI cable. …

FYI, the GPU is directly wired to the memory controller and is not PCI. Disk is full, you need to do some deleting. Some processes need temporary files, and if the disk is full, then they can’t function…one of those is X login.
