Cinnamon and Intel Integrated Graphics - Software Rendering Mode

[WharfRat]

I'm starting to grasp at straws here, but do any of these offer an alternative link

Code: Select all

update-alternatives --config i386-linux-gnu_gl_conf
update-alternatives --config x86_64-linux-gnu_egl_conf
update-alternatives --config x86_64-linux-gnu_gl_conf

I had the same issue with Virtualbox 5.2.0. After downgrading to 5.1.30 and ticked the display to 3D. The problem went away.

@WharfRat, the second command returns:

Code: Select all

update-alternatives --config x86_64-linux-gnu_egl_conf
There is only one alternative in link group x86_64-linux-gnu_egl_conf (providing /etc/ld.so.conf.d/x86_64-linux-gnu_EGL.conf): /usr/lib/x86_64-linux-gnu/mesa-egl/ld.so.conf
Nothing to configure.

The third command returns:

Code: Select all

update-alternatives --config x86_64-linux-gnu_gl_conf
There is only one alternative in link group x86_64-linux-gnu_gl_conf (providing /etc/ld.so.conf.d/x86_64-linux-gnu_GL.conf): /usr/lib/x86_64-linux-gnu/mesa/ld.so.conf
Nothing to configure.

The first one says there are no alternatives.

@Why Tea, was your issue with a virtual machine inside of VirtualBox or due to VirtualBox installed on a host Mint system? I do have VirtualBox installed, but this issue was occurring before I installed VirtualBox.

I have Mate in a VB and this looks awfully familiar to your results

Code: Select all

[bill@vb] ~ $ /usr/lib/nux/unity_support_test -p
OpenGL vendor string:   VMware, Inc.
OpenGL renderer string: Gallium 0.4 on llvmpipe (LLVM 4.0, 256 bits)
OpenGL version string:  3.0 Mesa 17.0.7

Not software rendered:    no
Not blacklisted:          yes
GLX fbconfig:             yes
GLX texture from pixmap:  yes
GL npot or rect textures: yes
GL vertex program:        yes
GL fragment program:      yes
GL vertex buffer object:  yes
GL framebuffer object:    yes
GL version is 1.4+:       yes

Unity 3D supported:       no

The only difference is the first three lines that you get:

Code: Select all

[intel_init_bufmgr:1193] Error initializing buffer manager.
libGL error: failed to create dri screen
libGL error: failed to load driver: i965

Are you running Mint in a virtual box or any virtualization environment

Ran across this concerning Intel graphics. Don't know if it might help with your situation or not but may be worth a read/try. The site belongs to and was written by a member here.
I have Intel graphics on a MintBox 2, applied the tweak and everything seems to be working fine ...

@Why Tea, was your issue with a virtual machine inside of VirtualBox or due to VirtualBox installed on a host Mint system? I do have VirtualBox installed, but this issue was occurring before I installed VirtualBox.

The issue is with a Mint VM running on a Windows 10 host. I googled and noticed it was a common issue with no obvious solution.

Note: I have also installed the same Mint iso alongside Windows 7 (i.e. on a separate physical partition) and there is no Software Rendering Mode issue.

This was precisely what I did with my Virtualbox downgrade:
- Noticed Rendering issue on VBox 5.2.0/Guest Additions 5.2.1
- Downgraded VBox to 5.1.30, removed Guest Additions 5.2.1 and installed Guest Additions 5.1.30
- After rebooting, the Rendering issue had diasppeared

I am no expert in this, but I suspect it is an issue with the Guest Additions...

Thanks Everyone!

JoeBingo, running the commands in your document didn't seem to solve the issue.

Linux Mint is NOT running inside of a VM. I do have VirtualBox installed as the Mint system is the HOST system for some of my VMs.
