As requested by @penalvch, checked what the BIOS offers. Answer: the BIOS does not offer to disable any intel or nividia chip.
In "Graphics Configuration", the BIOS only offers "DVMT Pre-Allocated" with values 64M 128M 256M 512M, currently set to default 64M. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1547077 Title: Some glyphs drawn consistently wrong, bug comes and go To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1547077/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
