Cannot change virtual display screen resolution using xvfb-metrics parameter

[jfhampton]

Hi,

I am using xvfb on linux ubuntu server 24.04 in UC mode with SeleniumBase 4.31.3.
I cannot get screen resolution to change when using parameter --xvfb-metrics to launch the test: screen resolution is always 1366x768.

Test is launched with following pamateters: --xvfb --xvfb-metrics="1920,1080"
UC mode is activated using context manager: with SB(uc=True, user_data_dir="my_user_dir_1") as sb:

I have traced the execution of SeleniumBase code and I see that setUp function is called after __activate_virtual_display_as_needed (in seleniumbase/fixtures/base_case.py).

Reading --xvfb-metrics parameter occurs in setUp function: __activate_virtual_display_as_needed gets empty self._xvfb_width and self._xvfb_height attributes and in result sets the default resolution (1366x768).

Am I using the xvfb parameters wrong ?

Nice catch. Thanks for reporting this.
Fixed in 4.31.4 - https://github.com/seleniumbase/SeleniumBase/releases/tag/v4.31.4

Thanks !
I have tested 4.31.4: resolution provided with parameter xvfb-metrics is applied to virtual display.
