Hello,
I am facing some issue with My Jetson Nano. jetpack 4.5.1.
I rebooted my jetson nano and got
“xlib: extension “nv-glx” missing on display 0”
When I clicked OK,
“unable to launch /usr/bin/startlxde x session”
comes.
How can I fix this issue?
I tried to install lxde over ssh session and now I am able to get lxde desktop but still problem at reboot and cant get default green desktop
Hi,
This is our method for installing lxde. Please take it as a reference.
Please reconfigure your window system from gdm to lightdm too. This was how we setup lxde on jetson nano 2gb.
•Use a lightweight display manager like LightDM. The LightDM service takes about 3 to 5 seconds to start.
To install and configure lightdm display manager, enter the commands:
sudo apt-get update
sudo apt-get install lightdm
sudo dpkg-reconfigure lightdm
NVIDIA recommends LightDM GTK+ Greeter as the default LightDM login greeter. To install this component, enter the commands:
sudo apt-get update
sudo apt-get install lightdm-gtk-greeter
All of them are at newest version. I am using jetson nano 4gb, not 2gb
What was your command to cause your system look like this so far?
I actually dont know, I was trying to run my detection script at reboot and use display to show output. I just put
@reboot /bin/bash /home/rrnivida/runner.sh to crontab
my runner.sh:
export DISPLAY=:0
cd /home/rrnvidia/jetson-inference/python/examples
python3.6 my-detection.py
I have just rebooted.
edit:
before trying my runner.sh, I tried to export DISPLAY=:0 from ssh.
So do you want to install the lxde or not?
I think I couldnt explain my point. my main problem is
“Xlib: extension “nv-glx” missing on display 0” error after reboot that I put some screenshot above.
After facing that error, I was able to install lxde to get some desktop but I want to fix the error and return to default desktop of jetson nano 4gb
We are not able to fix your main problem. The command you are using should not cause such problem. I would suggest you can directly reflash your board. Currently issue looks like one library is probably pointing to non- NV lib but however we are not sure.
What is runner.sh here?
It will be very hard for me to install and build everything again if I start from fresh sdcard.
runner.sh:
export DISPLAY=:0
cd /home/rrnvidia/jetson-inference/python/examples
python3.6 my-detection.py
I am using runner.sh to start detection and use display.
Please see what I have installed since previous reboot:

Please try to reproduce this error and share me the /var/log/Xorg.0.log.
This log file gives me some hints.
Your xorg does not use our normal driver. It is using the fbdev driver, which will not use graphic drivers that provided by jetpack.
For example, this is from your log. You can see that it is using the fbdev and modesetting driver.

You can see that your xorg does not load nvidia_drv.so, which is necessary for jetson graphic.
Thus, you can firstly check whether there is really nvidia_drv.so exist on your system now.
If it exists, then check what does your xorg.conf look like.
I see,
I think I made this while trying to run yolov5 with GPU which I couldnt succeed.
let me the drivers.
This is the only xorg.conf I can found in /etc/X11/xrdp/:
xorg.conf (1.4 KB)
And there is nvidia_drv.so in /usr/lib/xorg/modules/drivers/
What should I do with them?
Then the truth is you probably already removed the old xorg setting.
By default, this file should be under /etc/X11 and we also don’t install xrdp by default. It looks like there is great change on your device from the default jetpack.
Try to add this back to /etc/X11 as xorg.conf. If even this cannot work, then we have no idea about your device. Reflash it maybe a quick one.

There is a file /etc/X11/xorg.conf.jetson_e which is same as default.
I need to install xrdp to use VNC with headless jetson.
I made the changes you recommanded. my screen stays at:
Log:
Xorg.0.log (14.0 KB)
Now the issue seems from the kernel. Your xorg now is able to read the nv driver. But later it gets terminated.
Please share the dmesg.
