It was safe to proceed on this bold assumption that I could, because in all Ubuntu installations I&#8217;ve done the problem has not manifested itself until the first booting into the freshly-installed system. That is to say, the live CD does not have this problem, but displays the splash with no problems, so I knew there must be a way to make it work.<\/p>\n<p>There was <a href=\"http:\/\/ubuntuforums.org\/showthread.php?t=202934#post3763795\">a helpful link<\/a> on the Ubuntu Forums on <a href=\"http:\/\/ubuntuguide.org\/wiki\/Ubuntu:Gutsy#Fix_Slow_boot.2Ffaulty_splash_screen\">how to fix a faulty splash screen<\/a>. In the end, it was simply a matter of finding the right display mode -describing parameters for a couple of config files. As for the parameters, I initially tried to find them from the live CD, but apparently it&#8217;s using a different system from the one used by an installed Ubuntu (GRUB), so this path turned out to be harder than a simple trial and error.<\/p>\n<p>First I tried a full-blown 1280&#215;1024 pixels with 16.8M colors, which is the display mode that the desktop starts in and works just fine, but that didn&#8217;t work &#8211; which I probably could have guessed from the fact that the other config file, <code>usplash.conf<\/code>, already had this resolution.<\/p>\n<p>Then I thought about the way Windows XP boots on this system: the logo looks a bit crude, as if with a lower resolution and color depth than on the desktop. So I tried 800&#215;600 with a modest 256 colors &#8211; and already on the way down Ubuntu now displayed the splash screen! The reboot revealed final success: the splash screen now works.<\/p>\n<p>To be short but exact, what I did to make it work was:<\/p>\n<ol>\n<li><code>sudo gedit \/boot\/grub\/menu.lst<\/code> <br \/>so that at the very end of the first kernel line, after &#8220;<code>splash<\/code>&#8221; , I added <br \/><code>&nbsp;vga=771<\/code> <br \/>&#8211; this corresponds to the SVGA mode of 800&#215;600 pixels with 256 colors.<\/li>\n<li><code>sudo gedit \/etc\/usplash.conf<\/code> <br \/>so that <br \/><code>xres=800 <br \/>yres=600<\/code><\/li>\n<li><code>sudo update-initramfs -u -k `uname -r`<\/code><\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"<p>After installing Ubuntu 7.10 I could see it was still suffering from the annoying little bug all previous versions have: instead of the neat splash screen during booting, all I got was the LCD&#8217;s warning sign saying &#8220;Input not supported&#8221;.
