General :: Get Grub2 To Boot OS X With Graphics Mode Boot Option?
Apr 14, 2010
I've set up a triple boot system (Ubuntu Karmic, Windows Vista and OSX86 -- a patched OS X which works on a PC) on a Dell 9200 (C2D 2.13 GHz, 4GB RAM, nVidia G210). I sue Grub2 as the bootloader and update-grub picks up OS X and it boots without any problem.
However, although when booting OS X using its own Darwin bootloader, I can apply the boot option "Graphics Mode"="1680x1050x32" to ensure that I get the screen resolution that I want, when OS X boots from Grub2, the only resolution available is 1024x768 which is disappointing. I have tried adding gfxmode=1650x1050x32 to the OS X section of /boot/grub/grub.cfg in Ubuntu but this does nothing.

This started a few days ago and I checked back through recently installed packages and nothing looks related. If I boot into ubuntu normally, plymouth looks a mess, but then things boot fine but while the mouse is showing and ubuntu goes about with connecting to networks and so on, but it doesn't register the and input from the mouse or keyboard. It will sleep if you press the power button, but its no more responsive after waking up.
If I boot into recovery mode, and use the failsafe graphics option then everything runs fine. Apart from 3D graphics being pretty slow, which I can kind of understand. I get the same behaviour on all of the last three kernels. I'm running the latest maverick on an HP 6715b. i386 version although the processor is 64 bit compatible. 2Gb RAM.

I have just installed Ubuntu (9.10) and noted that in order to successfully run the trial off the CD I had to test in "safe graphics" mode. I have an NVIDIA GEforce 6600 GT card - which was discovered by Ubuntu in the first few minutes of the trial and so I activated the recommended driver and continued to test. After a successful trial I installed Ubuntu (dual partition Ubuntu / Windows XP), however, it seems the install didn't activate the required driver (as part of the process) and so I'm unable to get into my newly-installed Ubuntu at all. All I get is a flashing tty screen asking for my username and password - however it's erratic and won't recognise what I type. So - I'm stuck in a catch-22 as there doesn't seems to be a safe graphics mode option via the start (GRUB?) menu list.

I managed to set up my laptop to dual-boot Windows XP SP3 and Ubuntu 10.04. How do I set the Windows to be the default boot option at startup (GRUB2)?

After a lot of updates yesterday I have found that Lucid will no longer boot, I just get a blank screen that has a cursor flashing in the top left corner. I can't boot into recovery mode to see what the issue(s) might be because I took that option out when I ran update-grub.My question is this, is there a way to run update-grub -either from a live-cd or grub-rescue mode- that would put the recovery boot option back in? I have already edited the /etc/default/grub file to comment out the field.

In these days I install ubuntu 9.10 64bit on several notebook (Intel + AMD Switchable Graphics, NVIDIA Optimus Hybrid graphics), but the same problem is it can't boot ubuntu with graphic mode. I only can install it with text mode, and after installation, it still boot with text mode. I tried to execute startx, but failed to switch to graphics mode. I didn't see this issue with some notebooks with ATI/NVIDIA graphics, so I think this issue may relate with VBIOS VBE mode settings.
When I try to execute "startx" under the text mode, some error information appears as below.
(EE) open /dev/fb0: No such file or directory
(EE) No devices detected.
Fatal server error:
no screens found

Installed ubuntu successfully on the hard disk through live CD. My machine is a ASUS K40IN, with Graphics card GEForce G102M. Can't get ubuntu to run normally so I have to access through terminal in recovery mode. I need to install the drivers for the graphics card so I can run ubuntu in some form of gdm, otherwise I'm pretty much blind since I'm not too good with code.
/etc/x11/xorg.conf does not exist, so I can't use the exploit to get me to low graphics mode.
If there's a command I can enter into grub to run me in low graphics mode, anyone? I'm keeping [URL] and [URL] threads in view, since it's very possible I'm running into the same problems. I have the nvidia driver loaded on my ntfs usb stick ready to transfer and install but I can't seem to mount it proper. FailsafeX graphics mode does not work. I get a blank black screen.

I had been using Ubuntu 10.04.1 in a Macbook pro (triple boot: Mac, Win7 and Ubuntu). Now I am not able to boot in to Ubuntu in graphics mode. It just freezes after the Ubuntu logo appears. It happened once before and I re-installed the OS. Now I have the same issue. I can boot in recovery mode and get into my account.
When I tried startx command I get the error below:
(there is more stuff splashed on the screen, but the above two are the only errors I see)
I thought of reinstalling the OS. But this may happen again and re-installing the OS every month wipes out all my configurations and files in my account.

I was looking around and trying to find how to startup ubuntu in low graphics mode with out having to go through the recovery startup. So I was wondering if it is possible to boot into low graphics mode every startup? The reason is my computer is really old and runs faster in low graphics. Another question is what do I loose in low graphics mode?

how to enable boot in safe graphics mode in the bootable USB that I created for 10.04 by following the instructions in the download page.
Currently when I boot from USB and select installation, the monitor goes off. So I guess safe graphics mode is the way to go.

I have two hard disks sda and sdb. I have Windows XP installed on sda2 and Ubuntu 10.04 on sdb5. When I installed Windows XP, Ubuntu stopped booting. I tried to repair grub2 from a Live CD unsuccessfully. Now I have completely messed up my MBR of both HDDs. I just want to configure grub2 to load both OSes in dual boot mode.

I have a dual boot xp -ubuntu - AGP ati 2600 series radeon. Intel 8300 dell. The message comes up after login "ubuntu is running in low-graphics mode". I hit ok and I get 5 choices and none of them work.
1) run ubuntu in low-graphics mode.
2) reconfigure graphics.
3) troubleshoot the error.
4) exit to console login.
5) restart X.

I wanted to update my NVIDIA Drivers from the default to 256 (or whatever the latest is on their site). After the upgrade from their site and installing it through a command line, I've had trouble. For some reason, whenever I boot, I get the Kubuntu boot screen, even though I run plain Ubuntu. Also, after I boot it defaults to low graphics mode, and I have to hit "restart X" to make it run normal. Even then, visual effects won't enable, and games won't run, because apparently the "hardware device cannot be found". My attempts to revert back to old drivers have been unsuccessful; It says it's running the recommended right now, but I still have all these problems.

I installed 11.04 after Windows 7. when the GRUB boot menu starts up there is an option for Win 7 boot but it will not boot windows. When that option is selected the screen changes colour for 2 seconds and then reverts to the GRUB menu. Ubuntu boots fine.I downloaded the Boot Info Script and ran it, the results are

I recently got a netbook and setup as dual boot between win7 starter and 9.10 (64bit). Win 7 starter is not impressive so i want to nuke it and give the space all to my /USR partion. I am comfortable working with Gparted and assume that i can launch using my gparted live usb and delete the windows partion and then resize the /usr partion.
what changes do i need to make w/ Grub2? I would prefer not to see the Grub menu at all and have it load right the main kernel if possible. Also, if this is possible is there a way to get to the Grub menu during boot should i need to select a different kernel?

After installing karmic with Grub2 I am unable to boot into Archlinux partition. Grub2 has removed the last line of the Archlinux boot stanza! It used to read:-
[Code]....
Following the Grub2 tutorials I have tried editing /etc/grub.d/40_custom as follows:-
[Code]....
But no luck. Only way into Archlinux is to get into the edit shell and manually add the missing line and remove other stuff not needed. I have spent hours trying to resolve this issue and I am fairly p----d off

I was yesterday evening experimenting inserting a script into /boot/grub/grub.cfg. Well I broke grub.cfg and had to try to boot from a grub2 prompt.I have separate /boot and / partitions on /dev/sda1 and /dev/sda2 respectively.Working out the correct syntax for the boot to work was a little complicated, so I thought it would be useful to post the correct procedure here, in case anyone else has the same set up that I do (separate /boot and / partitions)At the grub prompt code:
grub> set prefix=(hd0,1)/grub
grub> insmod linux
grub> set root=(hd0,2)
[code].....

I'm as big a fan of Linux as Linus Torvalds himself but it's things like this that help to keep Linux from becoming mainstream. I mean, how would I ever explain the need for the following procedure to a non-techie type, recent or prospective Ubuntu convert? The following is not a question, as I have finally resolved the issue but is more of a rant, I guess you could say. The reasons that I decided to post it are:
1) To hopefully help someone else experiencing this issue.
2) To point out the need for significant improvement in the area of editing partitions under Ubuntu Linux.
3) To vent my spleen.

I am attempting to try install XUbuntu.
I loaded the dvd (one that came with Linux Format Magazine No. 139), changed BIOS to boot from dvd, and then:
I get the welcome screen with the options to boot Ubuntu, KUbuntu, XUbuntu or Boot from First Hard Disk. As I have an older laptop I was going to try XUbuntu. However, the arrow keys did not change the boot option. In fact nothing worked, Tab did not bring up a menu and Enter did not initiate boot.
I tried reloading the dvd, switching off the laptop (no way to shutdown) and restarting but always come up with the same problem.
My DVD drive works fine and the dvd appears not to be faulty since all the info is readable when it is loaded with windows running.
My system details are:
HP compaqnx9000
Mobile Intel Pentium(R) 4-m CPU 2.20 GHz 219GHz 704MB RAM
Optiarc DVD RW AD-7580A
Radeon 1GP 340M

I had Windows 7 installed on my system, then I installed Debian testing with grub2 as its boot manager.Initially I couldn't see windows entry in grub at all, so I ran:aptitude install os-prober kcpuload update-grub Now I can see the entry, but when I select it I get only Win7 system restore, instead of the the real thing. Any ides how to make it work?
EDIT: I tried the suggested approach to add a new file to /etc/grub.d, which generated an entry in grub.cfg, but it does not appear in the grub menu on boot :(
I have this:
grzes:/home/ga# cat /etc/grub.d/11_Windows
#! /bin/sh -e
echo Adding Windows >&2
cat << EOF
menuentry "Windows 7″ {

I'm using debian testing with grub2. Is there a way to stop the FS check at boot (something like ctrl-c) after the check has started and continue with the boot process as usual?.
