I might have to upgrade to 6.06! It's probably a regression/problem that has crept in because the developers and/or testers don't have the same hardware. And because laptop hardware is non-standard, it needs specific testing. Have you reported it as a bug? I don't know how much useful information you can supply, but it's unlikely to get fixed if the developers don't know about it. :-) Probably teaching you to suck eggs, but I just mentioned it for anyone else who's reading the thread.

So what is different with ubuntu 6.06, suse 10, knoppix - (and maybe more), which perform 'normally' for the hardware? It is Kubuntu 6.10 which is giving unusual problems. In fact on a few occasions, unpredictably, 6.10 has not booted properly in the laptop - the display seems not to start sometimes. I know that the hardware is not good, and not 'made' for linux, but a lot has been done with linux, and my experience here is that 6.10 is a small step backwards. I might have to upgrade to 6.06! -- alan cocks Kubuntu user#10391 -- ubuntu-uk@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-uk https://wiki.kubuntu.org/UKTeam/

You can also see colour depth expressed in terms of bits-per-pixel or bytes-per-pixel, e.g. 256 is 8 bits-per-pixel since 2^8 (2 raised to the eighth power) = 256. > > vga=791- VESA framebuffer console @ 1024x768x64k > vga=normal DON'T USE FRAMEBUFFER | Standard console > vga=790- VESA framebuffer console @ 1024x768x32k > vga=773- VESA framebuffer console @ 1024x768x256 > vga=788- VESA framebuffer console @ 800x600x64k > vga=787- VESA framebuffer console @ 800x600x32k > vga=771- VESA framebuffer console @ 800x600x256 > vga=785- VESA framebuffer console @ 640x480x64k > vga=784- VESA framebuffer console @ 640x480x32k > vga=769- VESA framebuffer console @ 640x480x256 > > I experimented long with these, and saw that the x256 choices, (773, > 771, 769) > all gave visible boot up image and progress bar - the 773 gave a nice > central display. > Unfortunately these all also led to very poor text/font display (in > kde, kubuntu). > > The poor text display became apparently good and normal again if I > restarted the xserver (ctrl alt backspace) Unfortunately, I can't solve this problem.

I think someone else mentioned removing the "splash" option from Grub, so try that. I think your problems stem from the non-standard hardware that is used in most laptops, which is not fully supported in Ubuntu (and probably not in most Linux distros).

Thanks, it shows some promise and the boot up image (kubuntu logo and graphic progress bar) although after the session has started it is apparent that the text is very poor.

If this works, edit the file /boot/grub/menu.lst and add it to the end of the commented "kopt" line. Then do a (if I remember correctly) dpkg --reconfigure grub and it should update all the kernel lines with the specified vga option. Then Bob's your Aunty's live-in lover.

[ubuntu-uk] (K)ubuntu 6.10 Inspiron 1100 boot up screen not visible
I installed Kubuntu 6.10 on a Dell Inspiron 1100 Laptop recently, and the boot up screens - kubuntu splash logo and the running text(?) (progress bar?) - cannot be seen. The live CD for 6.10 has problems with screen resolution and does not seem to complete even with the Safe graphics mode, I have to use the boot option F6 and append live vga=771 As it happens, 6.06 live CD boots normally for the laptop. With 6.10 how can I influence what screen resolution is used for initial boot activities? Background details: I know that this particular model of laptop has a problem with the bios not knowing or reporting the screen size, resolution properly - even a Dell CD install of XP produces a problem to be solved with particular driver magic. Anyway, the normal display is fine because I edited the xorg.config https://lists.ubuntu.com/archives/ubuntu-users/2006-September/094169.html -- Alan Cocks Kubuntu user#10391 -- ubuntu-uk@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-uk https://wiki.kubuntu.org/UKTeam/
