I am having issues with the latest 430 series drivers. When the driver is loaded my Dell 4k screen (P2715Q) turns off saying it does not receive a signal.
I tried various version of 430, but when I use the NVIDIA .run file to install the screen also turns of after the installer completes.
Debugging this is hard is there is no screen and at bootup ssh is not yet started when the screen turns off.
The older 418.74 driver just works fine, as is the nouveau driver.
Kernel: 5.1.16
OS: Fedora 29 x86_64
Monitor: Dell P2715Q, connected via DP to miniDP
Videocard: GeForce GTX 1070
There are no issues with 430.x when:
a connect another monitor (not 4k)
a connect both the Dell 4k and another monitor (!)
When only the 4k Dell is connected, the screen turns off.
the ‘–safe-mode’ run did complete (I cannot upload the gz file it seems).
One thing to note: after completing the nvidia-bug-report from a remote system and giving a shutdown cmd, the ssh session is terminated but the system never shuts down. Ping keeps working. Hard power off is needed to really turn off the system. nvidia-bug-report.log.gz (52.2 KB)
Since this is obviously a driver regression, maybe also mail it to linux-bugs[at]nvidia.com for additional attention.
Out of curiosity: in previous cases with this error, it was possible to circumvent it by simply enabling CSM in bios. Is this also possible in your case?
Right, got it. Check my BIOS, CSM was already on. Disabling it makes it worse. Then even a dual monitor setup does not work. Then both monitors go into power safe.
The workaround is not friendly: On boot, If I plug the monitor onto the onboard vga and wait for the initial output, then I can re-plug it onto NVIDIA card and it will work.
@lintweaker, would you check if that works for you as well?
Also, if it helps, there’s a log entry that is present when using 430.xx that is not present on previous versions:
nvidia-modeset: WARNING: GPU:0: Lost display notification (0:0x00000000); continuing.
@kriansa, the other issue you referred to indeed seems the same.
Currently I am back on 418.74 as a workaround or I can use my ‘temporary dual screen a boot’ trick. But I think now it is time for Nvidia to step in :-)
I tried on system Precision T7610 which has Genuine Intel(R) CPU @ 2.30GHz; installed Ubuntu 19.04 with kernel 5.0.0-13-generic; GTX 1070 + Driver 430.34 and used 4K display but not able to repro issue.
Can you please provide xrandr output and confirm if you are using dongle or DP cable to connect display.
