nRF connect for desktop BLE & DTM apps opens with a blank window

[eyalasko]

Hi,

Like many posts before I'm facing blank white screen when trying to run nRFCOnnect for desktop (3.4.1) BLE app (2.4.0)

Tried to:

• Restart PC
• Uninstall-reinstall 3.4.1
• Uninstall-reinstall 3.4.0
• Uninstall-install latest nrf command line tools-reinstall (link)
• Use nRF52840 (PCA10056) dongle
• Use nRF52832 (PCA10031) dongle
• Use another fresh nRF52840 dongle

all to no avail....

Same blank screen occurs on all other NRFConnect's apps: DTM, RSSI viewer, Programmer but NOT with the toolchain manager... implying it stems from (probably) the same root cause (jlink driver? graphic library?)

Any advise ?

I'm on Kubuntu 22.04 and same is happening to me after an update. nRF connect for desktop and the ble standalone are fully up to date but after selecting a device in ble standalone the window goes blank white and ctrl+r just causes it to close.

I was able to reproduce the issue on a second system. It worked until i performed an apt upgrade. So it must be related to any of the packages listed below

I downgraded  libstdc++6  to an older version and my application works again

Hi, 

Thanks for the tip regarding downgrading libstdc++6 to and older version. I have also seen post where they a mix between 32 bit NRF command line tool and nRF Connect for desktop 64 had resulted in a white screen. 

However I would point out this initial case was created over 3 years ago and we recommend creating new cases instead of reviving old cases.

If not too complicated, can you share how you downgraded libstdc++6 ?
I have the same blank screen since today (was working perfectly yesterday), I'd like to confirm that this is the same issue.
Thanks !

I don't have a linux computer today, but it used to be something similar to this

sudo apt install pkg_name=version

You may want to uninstall the current version you have installed

sudo apt remove pkg_name
