Handling Process

    Note: Here we can determine that the issue is due to the qxl version(1.20.8) is higher than the version our support(1.20.4).

  3. Next, find the qxl-version.info file in the VDI directory.

  4. Use vi to edit the qxl-version.info file and enter 1.20.8=1.20.4 at the end of the line.

  5. Save the changes to the file and reboot the VM.

  6. Login using VDI Client again.

Root Cause

qxl version 1.20.8 is higher than the supported version.

Solution

After updating the QXL version to 1.20.4, the virtual machine’s resolution can adjust dynamically
