Code:
sudo update-grub
to pick up these changes.
For trying new modes... you should be able to bring up the Grub menu by pressing the shift key a few times as it's booting up...
ok I did the edit to the grub file and it did change the resolution on the vga monitor, but did not help with s-video output. it's not actually outputting anything to s-video with vga plugged in, and with s-video only pluged in it gives a brief signal at the purple splash screen but I don't get the ubuntu logo and it stops any output again. now i did find out that if i hold shift on boot and select the previous version of linux it will output to s-video and vga at the same time just fine.

Hmm... So that may be related to a similar kernel problem that "taygan" was having here:

First of all, THANK YOU SO MUCH for an excellent troubleshooting thread. It helped me isolate my problem.
Clean install Natty 11.02 on a Gateway M-1625 with a ATI Radeon x1270 (RS690M). Note that this Radeon is no longer supported by fglrx (ATI Catalyst). After pulling my hair out for 24 hours, and trying every combination on the grub menu, I finally fixed my "blinking cursor/blank screen/fixing recursive fault but reboot is required" by downgrading the kernel to 2.6.37
First, the USB stick live desktop i386 booted to Unity fine, but Unity won't run installed (no 3D graphics??) - guess that's another issue. Next I tried installing over my 10.10 partition. It booted to rescue (recovery?) and low graphics most of the time. I thought it was a bad install so I formatted the partition and did a CLEAN install of Natty 11.04.
Grub always boots fine, it was hanging/black screen/sometimes blinking cursor after selecting the kernel. I tried many many combinations on the kernel boot line (pressing e from the grub menu): deleting everything ("quiet" "splash" and the "vt...7" thing) on the line after "ro" and trying different options (I always used "nosplash" to see what was going on - remember don't use the " when using options - it's just for reading clarity)
"nosplash text" + "nomodeset" or "radeon.modeset=0" or "xforcevesa" would SOMETIMES work, but would often hang at "fixing recursive fault but restart is needed" Other times it would hang after 3 lines, or after a few screenfuls, depending on the options, and sometimes changing with the SAME options. Grrr...
Finally, it looks like acpi is mucking things up with the latest kernel for me: The options "ro acpi=off nosplash text" can consistently get me booted to a terminal. Then from the terminal "sudo service start gdm" gets to the gdm logon screen. On the logon screen I must choose "classic (no effects)" and then I can get to gnome.
From there I downloaded the older kernel and installed it from the .debs found in the Ubuntu Kernel Mainline PPA,
If I select "older Linux Kernels" (I think that's what it says) from the grub menu and boot to 2.6.37 everything seems to work fine.
Older debs found here:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.37.6-natty/
for 32-bit i386 download and install in this order:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.37.6-natty/linux-headers-2.6.37-02063706_2.6.37-02063706.201103281005_all.deb
http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.37.6-natty/linux-headers-2.6.37-02063706-generic_2.6.37-02063706.201103281005_i386.deb
http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.37.6-natty/linux-image-2.6.37-02063706-generic_2.6.37-02063706.201103281005_i386.deb
if you're running amd64, be sure to download the headers-all, headers-amd64, and image-amd64 - but I don't know if this workaround is needed with the 64-bit kernel.
Be sure to install (click on) the .debs in order: headers-all, headers-i386(amd64), and image-i386(amd64)!
Thanks to this blog post for the inspiration:
http://www.khattam.info/howto-instal...010-11-13.html
So Installing an earliar version of the kernel as he described (above) my help you... If you need the debs for the AMD64 / 64bit kernel debs... let me now and I'll post them.

Most of it ws fine for me just a few clarrifications needed here and there.
After struggling with this for the best part of 2 days, I've finally made some progress, however small.
Even with the revised changes to the kernel boot line you suggested, I couldn't even get into text mode. This particular system is a laptop with nvidia 8600m GS graphics. I eventually booted it with an external monitor connected and it boots into a console pretty much whatever I put in grub. The output is displayed on the laptop screen only. It just seems to need be connected to a monitor to force it into some other mode or something.
Anyhow, nvidia-current is already installed and I have created an xorg.conf. When I try to start gdm i get "gdm start/running, process 2591" then it quickly returns to the command prompt.

I'm experiencing the same issue with that earlier version as well, the kernel that does work for me is 2.6.35-28 is there a way to just make that load by default for right now?

Re: Graphics Resolution- Upgrade /Blank Screen after reboot
Upgraded from 10.10 to 11.04 on Friday. Screen went black on reboot.
Previous versions(for example: 2.6.35-28 ) would boot up fine.
Dell Latitude D630
Graphics card: NVIDIA Quadro NVS 135M
Thanks to all the suggestions, after 2 days of trying different things suggested in this thread, I finally got my system to boot with 2.6.38-8.
1) changed /etc/default/grub
Code:
GRUB_CMDLINE_LINUX_DEFAULT="acpi=off splash"
and subsequently ran
Code:
sudo update-grub
I haven't checked Unity desktop yet, but Gnome desktop is working normally as before.

Re: Graphics Resolution- Upgrade /Blank Screen after reboot
so i tried to upgrade from the last version to the current 11.04
made a live usb, and it worked flawlessly whilst booting from usb
install seemed to go well
now when i boot from HDD i get splash screen, log in to my user account as usual, then all hell breaks loose
generic ubuntu background occasinally interupted with flashing boxes of text, that seem to be various upgrade requests, etc but no desktop, nothing as far as hot keys working blah
again, running 11.04 off of live usb is working fine.
wtf? lol any ideas for this total idiot?

Hmm. I know this chip was Ubuntu challenged until about a little over a year ago when they made some driver changes, but has been fine since then, through the 195 series of drivers.
NVidia 8600 graphics on which/what kind of laptop? Laptop's add a few more variables such as "backlighting." I have quite a few various nvidia cards here and I've always had a liking for their chipdets. What I've noticed on them is that from the start "nomodeset" usually turns off KVM long enough to get the nVidia drvers loaded...
Please post your xorg.conf and your ~/.xsession.errors and we'll see what may be going on.
