Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.

RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description David Jaša 2015-11-25 16:16:45 UTC

Description of problem:
qxl driver offers resolution that don't fit to video memory (> 2560x1600 or 2048x2048)

Version-Release number of selected component (if applicable):
qxl-win-unsigned-0.1-24
guest OS tested: XP, 64b Windows 7

How reproducible:
reproducible on XP
not reproducible on 64b Windows 7 (32b 7 not tested)

Steps to Reproduce:
1. run VM with default video memory settings (ram/vgamem/vram: 64/16/64 MB)
2. install qxl driver
3. change resolution from OS applet (right click Desktop -> Options)

Actual results:
modes beyond 2048x2048 or 2560x1600 are offered on XP

Expected results:

Interesting, we'll investigate but not in the scope of 3.6, definitely not a blocker.

Comment 3 Pavel Grunt 2015-11-26 10:13:28 UTC

It offers the higher resolution but with reduced color depth (16b instead of 32b)
