Change Splash Screen Resolution?

[sting547]

I've recently upgraded to Ubuntu 10.04 LTS. When I boot up I see this:

in a very low resolution

At the login screen and on the desktop my resolution is 1680 x 1080

Is there a way to make the splash screen that resolution as well?

Thanks in advance

Have you installed propriety drivers for your graphics card? If so, disable them, then plymouth (the new boot splash) should automatically detect your resolution. Disabling the propriety drivers will disable any desktop effects you have running (such as anything graphical to do with compiz).

Otherwise, try running 'sudo dpkg-reconfigure plymouth'.

If you are running nVidia graphics, there is apparently a bug with the nVidia video drivers which lowers the resolution of Plymouth. This is how I got around it:

1) Open Terminal
2) Run: sudo gedit /etc/grub.d/00_header
3) Go to line #103, which should read: set gfxmode=${GRUB_GFXMODE}
4) Add the following to the next line (#104): set gfxpayload=lengthxwidth (where length and width are the dimensions of your screen)
5) Save
6) In Terminal, run: sudo update-grub

That should do it. If set gfxpayload=lengthxwidth doesn't work, then try set gfxpayload=keep.

I think u can change it using the GUI app:

startup-manager.

I think u can change it using the GUI app:

startup-manager.

I don't think startup-manager has been modified for plymouth yet.

I don't think startup-manager has been modified for plymouth yet.

But it still works though. After unsuccessfully trying to sort this issue out, at the end I used startup-manager for setting plymouth resolution (not 1440x900, which I use, but 1280x1024: not ideal since this is not a right ratio, but still better than 640x480). If someone finds out how to use native ratio (16:10 for 1440x900) or tested this resolution with the approach by softpedia godsiem mentioned in the previous post, please post here.

Just to clarify, by length you mean height, right?

I'll try this.

It certainly seems to have improved things, (using set gfxpayload=1440x900), but the quality still looks awful. I wonder if sticking x32 on the end of that would make any difference.


EDIT: It didn't.

@WorMzy
By length and width, I mean width and height, respectively (sorry about the confusing language). Also, I forgot to ask whether you have already changed the GRUB_GFXMODE setting in your /etc/default/grub file.

My grub file looks like this:

# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.

GRUB_DEFAULT=0
GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=3
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX=""

# Uncomment to disable graphical terminal (grub-pc only)
#GRUB_TERMINAL=console

# The resolution used on graphical terminal
# note that you can use only modes which your graphic card supports via VBE
# you can see them in real GRUB with the command `vbeinfo'
#GRUB_GFXMODE=640x480
GRUB_GFXMODE=1600x1200

# Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux
#GRUB_DISABLE_LINUX_UUID=true

# Uncomment to disable generation of recovery mode menu entries
#GRUB_DISABLE_LINUX_RECOVERY="true"

# Uncomment to get a beep at grub start
#GRUB_INIT_TUNE="480 440 1"

Notice the section in bold. The resolution of the grub splash screen must be in 4:3 ratio. I'm wondering whether that is why your splash doesn't look as nice since 1440x900 is in 16:10 ratio. I'd try maybe 1200x900. I set my gfxpayload to the same resolution as my GRUB_GFXMODE.
