Display bug on resolution > 800 / ubuntu 14 on VMware

Asked by ubuntu-tester

Hi everybody,

I installed an Ubuntu VM on several desktops (Windows). I have a problem with the resolution. Everything is ok on 800x600.

If I change the resolution to something higher than 800 (eg: 1024x768..), then, everything after the 800th pixel is mirrored on the first 800 pixels.

Running a Linux 3.13.0-29-generic x86_64 x86_64 on VMware 6.0.2 Everything updated (dist, package, vmware).

I have not this problem with generic kernel 3.13.0-24.

cf. http://askubuntu.com/questions/485417/display-bug-on-resolution-800-ubuntu-14-on-vmware

Any ideas on how to solve this problem ? Is-this a bug related to the kernel 3.13.0-29 ?

Thanks in advance, have a good day !

This bug appends when using a virtual machine installed in VMPlayer 5.0.x on VMPlayer 6.0.x :

See solution : https://communities.vmware.com/message/2398804#2398804

"Here's what's happening: The VM is created on a very old version of player or workstation, and it's official virtualHW version is 7. This causes the X server driver dispatcher to enable the old legacy driver that is not at all compatible with vmware fbdev. Still Ubuntu has forced fbdev on for 12.04, and there is a clash. By coincidence it happens with this upgrade, but it could have happened much earlier.

Remedy: 1: Update the VMs view of the virtual hardware:
0. BE SURE TO BACKUP YOUR VM, BE IT USING SNAPSHOTS OR A COPY
1a, For Workstation 9 or above owners, just run "Upgrade this VM"
1b (Completely unsupported and unrecommended) For player players: Get a recent vmware player, Change the .vmx file line virtualHW.version = "7" to "9" and fire up the VM. Verify that everything seems to work before proceeding.

Remedy 2: Disable vmwgfx fbdev in ubuntu.
0. BE SURE TO BACKUP YOUR VM, BE IT USING SNAPSHOTS OR A COPY
1. Edit the VM file /etc/modprobe.d/vmwgfx-fbdev.conf to say
options vmwgfx enable_fbdev=0
2. Run
sudo update-initramfs -u
3. Reboot"
