Description Giuseppe 2019-10-04 12:38:15 UTC 
Description of problem:
I have installed a Windows 10 VM using a 7" display with a 800x480 screen resolution. The qxl driver used is the: qxl-wddm-dod-0.19 but the minimum resolution available on Windows 10 display settings is 800x600.

There is already a similar Bug ID: 1477492, but this issue could be present again with another small display with a different resolution.


Version-Release number of selected component:
qxl-wddm-dod-0.19

How reproducible: always


Steps to Reproduce:
1. install a Window 10 VM on a machine with a small monitor
2. Go to Windows display settings
3. Try to set a correct resolution but only the 800x600 resolution is available

Actual results:
Invalid screen resolution

Expected results:
Correct 800x480 screen resolution available on the list of supported resolution

Additional info:
I have changed locally the code and I have a working version signed with a developer certificate. Is there any side effect to set a MIN_WIDTH_SIZE to 320 and MIN_HEIGHT_SIZE to 200 instead of 800 and 600?

In general, Win10 requirements include display of 800x600
https://www.microsoft.com/en-us/windows/windows-10-specifications#primaryR2
Attached driver that includes lower resolutions (800*480 and also lower up to 320*200, if available).
Please respond whether it works as expected.

I just spoke to the KAL engineers. They were able to verify the code on their simulated environments on a laptop, but did not yet have access again to the real ATM hardware. Access to the hardware is unfortunately a bit of a bottleneck here as the machine is currently running different tests by the bank. As soon as this is finished, Giuseppe will verify the code on the real ATM and update the BZ.

Thanks for the super-fast turn-around!
Comment 6 Giuseppe 2019-10-22 16:25:13 UTC 
Hi,
I have tested the driver on the machine and it works properly.

Thanks,
Giuseppe
Comment 7 David Blechter 2019-12-17 15:27:56 UTC 
The plan is to release the new version of the driver in rhel 8.3
Comment 8 Giuseppe 2020-01-16 07:34:15 UTC 
Hi,
Testing the drivers on some machines having the monitor in portrait position, the windows screen is shown flipped. Is it possible to add the "portrait (flipped)" and also the "landscape (flipped)" configurations to the QXL as for standard windows driver?

Best Regards,
Giuseppe

Hi,
Please, open a new BZ for this new requirement.

thanks David
