[Bug 480159] Re: grub console is ridiculously slow
Workarounds are using - GRUB_CONSOLE=terminal - or lowering the resolution The problem here is that EFI GOP is framebuffer based console with no video acceleration. At a high resolution it's very CPU intensive to draw in that. I suspect this could be somewhat by optimizing the GRUB code more. ** Changed in: grub2 (Ubuntu) Importance: Undecided => Wishlist -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/480159 Title: grub console is ridiculously slow To manage notifications about this bug go to: https://bugs.launchpad.net/grub/+bug/480159/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I too am affected by slow console when GRUB_TERMINAL_MODE is set to gfxmode in GRUB 2.04 and earlier versions. I believe this problem is not resolution-specific; but suffers under VBE mode.

Same problem here with a ThinkStation S20, Nvidia Quadro 2000, and grub 2.02~beta2-9ubuntu1.3. Apparently the default is to use the monitor's full resolution of (in my case) 1920x1200, causing the bug to appear. It's obviously not a big problem, but it's quite irritating.

[Bug 480159] Re: grub console is ridiculously slow
I'm experiencing this with the NVIDIA Quadro FX 500/600 AGP (if I remember correctly), and ONLY on the DVI port--both when using a DVI monitor or a DVI to VGA adapter. Using grub2-2.02~beta2-15 on Ubuntu MATE 14.10 which by default uses a graphical theme (grub2-themes-ubuntu- mate), so I don't know if I'm experiencing a better or worse degree of slowness. Rather than using the monitor's 1280x1024 resolution as do Linux and grub2 on other machines, it seems to fallback to 640x480 and very few colors, and unless I pass a kernel argument (e.g. vga=795) the console output is unreadable white blocks. The drawing speed seems slightly faster on one of the machines--which I assume is due to a faster FSB (533MT/s vs 400MT/s, since they both use AGP 4x and the one that draws slower has a faster CPU clock: 2.9GHz vs 2.4GHz). If I use GRUB_GFXMODE=1280x1024 in /etc/default/grub, it behaves much faster and in full color, just like when using the VGA port. Fast forward to 2014, and I can find various reports of similar bugs but for quite a variety of hardware, and some of which have been resolved. I should be able to collect the output of vbeinfo if desired. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/480159 Title: grub console is ridiculously slow To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/480159/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
