Update kernel to RHEL 6.8 version on a system on VMware. 2. Update xorg-x11-server-Xorg and xorg-x11-drv-vmware to latest 3. xrandr --output <output> --mode 1600x1200 Actual results: Unable to set resolutions above 1280x1024 Expected results: Should be able to set higher resolutions supported by driver. Additional info: It appears that vmgwgfx.ko module has been introduced with RHEL 6.8 for direct rendering. The issue is seen only on RHEL 6.8 kernels. RHEL 6.7 and earlier kernels didn't have this problem.

The workaround found was to boot with kernel-2.6.32-573.26.1.el6.x86_64 kernel.
We will try to reproduce this at VMWare and update this issue.
Update WW11.3 Summary: Reproduced this issue in RHEL6.8 with kernel-2.6.32-642.4.2.el6.x86_64 based on above steps. ENV: Host: ESX6.0 Guest: kernel-2.6.32-642.4.2.el6.x86_64 xorg-x11-server-Xorg-1.17.4-16.el6_8.x86_64 xorg-x11-drv-vmware-13.1.0-2.el6.x86_64 00:0f.0 VGA compatible controller: VMware SVGA II Adapter Reproduced Steps: 1.

Could you please attach output of glxinfo and vmware.log file. Thanks
It seems max vram size is the limiting factor here to increase the resolution. From logs we can observe: Maximum display memory size is 9024 kiB This KB article can be helpful in increasing the resolution of guest OS: https://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1003 [drm] Initialized drm 1.1.0 20060810 vmwgfx 0000:00:0f.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16 [drm] DMA map mode: Using physical TTM page addresses.

Could you please also make sure the below patch is applied to kernel for VRAM issue: https://cgit.freedesktop.org/mesa/vmwgfx/commit/?id=40ed03e115bbfb7dea28447166e3e02635abbdbd

Retested in RHEL6.9 with kernel 2.6.32-696, also reproduced this issue. So can we make a rhel6.8 or rhel6.9 build with this patch? and i can verify it again.
CC Rob Clark who used to deal with vmwgfx related fix
Hi, Update from QE side. We have confirmed RHEL 7.3 has fixed this issue, and the patch for the fix is probably as VMware's mention in Comment 11. As our test result is: The kernel build kernel-3.10.0-499.el7 can reproduce this issue, and kernel-3.10.0-500.el7 has no this issue. So I suggest that either recommend customer to upgrade to RHEL 7.3. Or if customer insist to stay on RHEL 6, then we may need developer and PM decide whether the fix can be back-ported. In this case, we QE are pleased to verify the fix. Thanks!
Red Hat Enterprise Linux 6 transitioned to the Production 3 Phase on May 10, 2017. During the Production 3 Phase, Critical impact Security Advisories (RHSAs) and selected Urgent Priority Bug Fix Advisories (RHBAs) may be released as they become available. The official life cycle policy can be reviewed here: http://redhat.com/rhel/lifecycle This issue does not appear to meet the inclusion criteria for the Production Phase 3 and will be marked as CLOSED/WONTFIX. If this remains a critical requirement, please contact Red Hat Customer Support to request a re-evaluation of the issue, citing a clear business justification.

WW24.1 Update: The workaround has been documented here: https://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1003 Steps for workaround: 1. Power off target VM 2. Modify VM's vmx file: svga.vramSize = "20971520" svga.maxWidth = "2560" svga.maxHeight = "2048" 3. Power on target VM 4. Set your larger resolution with xrandx
Hi, Deepu K S As shown in comment 21, we have confirmed the VMware workaround works for this issue. It seems that this bug can not be fixed in RHEL 6 anymore, but I think you can tell customer to use this workaround.
