Additional remark: I noticed slight differences in the kernel log regarding console mode initialization:
Console: colour dummy device 80x25 (when 1G) vs. Console: colour VGA+ 80x25 (when 2G). When disabling the graphical terminal in GRUB (GRUB_TERMINAL=console), grub actually runs at normal speed again; but the subsequent OS startup process remains unchanged slow (probably because console mode is changed again). There appears to be some correlation between the presence of 2GB memory/dual channel access and the selected video mode; I however do not understand what is going at low level, possibly a bug in system BIOS. Can someone help or offer a workaround? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/816035 Title: Memory upgrade makes Ubuntu painfully slow To manage notifications about this bug go to: https://bugs.launchpad.net/null/+bug/816035/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
