newyorkcity Posted April 26, 2008 Share Posted April 26, 2008 No matter which version of Ubuntu I install, no matter if it's 32 or 64 I always exprience this. When the system is loading, after I see the first screen like lthat loading bar going right and left to right etc then the monitor goes into sleep mode but the system still loading and after maybe a minute or so, I get to see the login screen. When I sinatll Ubuntu, version and build 32 or 64 doesn't matter, I get the same problem. After first prompt/screen the monitor goes into sleep mode, the system continues for a while as I can see/hear the PC running with the disc. Why in the world it acts this way. When I install any other OS, ex: Win/Fedora/others, I see every single screen that is during the installation and after it every screen as loading and anything like that. The monitor neve goes in sleep during the loading with any other OS beside Ubuntu nor as I added . My specs ar ProView 17", DFI mb, 4GB DDR2, 660GB SATA2, AMD 64 4000+. Please help.

markwolfe Veteran Posted April 26, 2008 Veteran Share Posted April 26, 2008 It sounds to me that Ubuntu is initially setting your resolution or frequency too high for your monitor. During that time, your monitor will not display anything. When Ubuntu later changes to something your monitor can handle (sounds like at your gdm login screen), you can once again see the display.

markwolfe Veteran Posted April 26, 2008 Veteran Share Posted April 26, 2008 :p Knowing why something is behaving the way it does, and being able to do something about it is a very important distinction. I never knew about usplash.conf. Nice to learn something new for the day :yes: Now... what old thing to forget? :ermm: Link to comment Share on other sites More sharing options...

newyorkcity Posted April 27, 2008 Author Share Posted April 27, 2008 Any further inputs about this matter? Link to comment Share on other sites More sharing options...
markwolfe Veteran Posted April 28, 2008 Veteran Share Posted April 28, 2008 Well, since this is during the boot process, before X has started, we need to fix this someplace other than xorg.conf. The xorg.conf file handles the video settings for X, but this doesn't apply until X is started to display the gdm screen (which works). The setting you are looking at is possible setting of your VESA mode in your kernel boot line in your /boot/grub/menu.list file. Adding a parameter such as vga=791 will force a specific VESA resolution and color depth to your video hardware. It may be possible that you need to pick a different usplash VESA mode. I'm not sure where the kernel parameter and the usplash app change control (or if they pass the mode from kernel to usplash). This area is a mystery to me, because I have never played with it. Here is a link to some more info on customizing usplash, if you find it helpful (and it contains the ability to set VGA modes, just like the kernel line). http://help.ubuntu.com/community/USplashCustomizationHowto Link to comment Share on other sites More sharing options...
