Created attachment 1217454 [details] Xorg.0.log for RHEL 6.8 VM starting X with 1280x1024 default resolution and 8 MB VRAM Description of problem: Version-Release number of selected component (if applicable): Driver: xorg-x11-drv-vmware-13.1.0-2.el6.x86_64 Kernel: 2.6.32-642.6.2.el6.x86_64 How reproducible: Always, I believe. Steps to Reproduce: 1. Create RHEL 6.8 VM on VMware ESXi 5.5U3 with X Windows configured to run 2. 8 MB VRAM for (virtual) video card is allocated automatically (i.e., svga.vramSize = "8388608" in the ESXi config) 3. Start VM so that it boots into X (VM starts at 1280x768) 4. Log in 5. Select System->Preferences->Display and select 1280x1024 from "Resolution" dropdown 6. Click "Apply" Actual results: The screen splits into four (not all equal) parts and is unusable. xrandr output (prior to changing resolution): Screen 0: minimum 1 x 1, current 1280 x 768, maximum 8192 x 8192 Virtual1 connected 1280x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm 1280x768 60.00*+ 59.87 1600x1200 60.00 1680x1050 59.95 1400x1050 59.98 1280x1024 60.02 1440x900 59.89 1280x960 60.00 1360x768 60.02 1280x800 59.81 1152x864 75.00 1024x768 60.00 800x600 60.32 640x480 59.94 Virtual2 disconnected (normal left inverted right x axis y axis) Virtual3 disconnected (normal left inverted right x axis y axis) Virtual4 disconnected (normal left inverted right x axis y axis) Virtual5 disconnected (normal left inverted right x axis y axis) Virtual6 disconnected (normal left inverted right x axis y axis) Virtual7 disconnected (normal left inverted right x axis y axis) Virtual8 disconnected (normal left inverted right x axis y axis) Expected results: In a RHEL 6.7 VM (kernel: 2.6.32-573.el6.x86_64, xorg-x11-drv-vmware-13.0.1-9.el6.x86_64) with the same 8 MB VRAM allocation, I get resolutions up to 1600x1200 including 1280x1024. 1280x1024 should work with 8MB of VRAM in RHEL 6.8 as well. (It should actually work in 5 MB, I believe, as it did in RHEL 5) Additional info: It appears that the 1280x768 is properly restored by pressing <Ctrl><Alt>+<Backspace> to restart X. In the same RHEL 6.8 VM if I set the VRAM allocation to 10 MB (svga.vramSize = "10485760"), the 1280x1024 resolution works.
