I was able to reproduce this issue with a previous hardy kernel, 2.6.24-23.52, and can confirm that the kernel in hardy-proposed, 2.6.24-24.56, improves the handling of these characters. One issue I did notice is that the screen blanking due to inactivity doesn't end up applying to the characters with the brightness bit set; however, I've verified this also happens with the unpatched kernel, so it's not a regression introduced here (ah, that's bug 395374).

Typically about one national character missing. I try to summarize all information I have collected in this new general report and mark the earlier reports about special cases as duplicates. Several non-ASCII characters get corrupted in the framebuffer console. (see attached photos) This happens when returning from X back to the console using Ctrl-Alt-F1 ... Ctrl-Alt-F6. The characters are are displayed correctly when booting into single user mode and not starting X. (see attached intrepid-single-user-OK.jpg) So the problem is not incomplete font implementation or some locale issue. This is why I report the bug to the kernel instead of to console-setup, if feels that console-setup should not cause random pixel characters (But of course the bug could really be somewhere else. I'm far from understanding completely how this all works.) I also attach my /etc/defaults/console-setup Actually the problem is described in /usr/share/doc/console-setup/FAQ.gz However, it says that this happens only in text mode, not in framebuffer mode. So how can I find out in which mode my console is actually running? I believe that my console should be in framebuffer mode, because: $ lsmod | grep fb fbcon 47648 0 tileblit 10880 1 fbcon font 16512 1 fbcon bitblit13824 1 fbcon However there is a file /etc/modprobe.d/blacklist-framebuffer and it says # Framebuffer drivers are generally buggy and poorly-supported, and cause # suspend failures, kernel panics and general mayhem. For this reason we # never load them automatically. So do we use fbcon, but not the underlaying framebuffer??? Some documentation is here http://www.mjmwired.net/kernel/Documentation/fb/fbcon.txt, but I'm still confused. The problem is not specifc to the reported kernel version. I see it also with the current Hardy kernel and the Jaunty Beta LiveCD (see jaunty-liveCD.jpg). The problem is not specific to the reported grahics card. I see it also on Nvidia, on Radeon, and also on the virtualized card created by VMware. The previously reported bugs (now linked as duplicates) cover also various hardware and software configurations. I have tested the range Unicode U+00A0 ... U+00FF, my console coding is UTF-8. http://www.utf8-chartable.de/ can be used for referece. (From the previousily reported national character issues I conclude that also characters outside this range are affected) You can easily test yourself using the attached file $ cat sampletable.txt The character corruption comes in 2 different forms: - Random pixel character range: All characters between and including U+00E9 and U+00FF are corrupted. Often the pixels are completely random (See attached intrepid-random-pixel-range.jpg) and they are different on each console tty1, tty2, ... Sometimes they are just all white or black. The somehow weird thing is that the U+00E8 (e grave) is always the last character displayed correctly, whereas U+00E9 (e acute) is always the first corrupted character. - missing accents. There is no random corruption in this case, but accents are missing from capital letters. It looks more like an intentional low-grade variant of the font. Accents are present on lowercase letters. A couple of very rare characters (e.g. thorn) are displayed as white blocks. (see attached intrepid-no-accents.jpg) I guess this variant of the problem may lead to the belief that a certain configuration is not affected, if you just test a couple of lowercase characters. The same kernel on the same machine can sometimes show random pixel character range and sometimes missing accents. E.g. when boot first into single user mode and start your X later in contrast of starting everything the standard way. (intrepid-random-pixel-range.jpg and intrepid-no-accents.jpg are from the same machine using the same kernel) P.S. Not sure how important this problem really is. I started to dig when investigating some serious display corruption (affecting also X on framebuffer 7)

Re: [Bug 355057] Re: Non-ASCII characters get corrupted in framebuffer console
No character corruption occurs anymore in my sampletable.txt in tty1 ... tty6. Correct characters seem to be displayed all the time. (Well I have not double checked every single character with a Unicode table. But those characters I happen to know by heart are correct and all other look correct to me) Great to hear. However, the characters previously corrupted appear in a different color now. While all characters, which worked before are displayed in some kind of grey, the new characters are displayed in white. Any explanation for this? The problem is already mentioned in https://bugs.launchpad.net/ubuntu/bugs/303561 The setfont(8) man page mentions that only 8 instead of 16 can be displayed if a font has more than 256 glyphs. But I understand this affects the whole console and not only the last 256 glyphs. If this understanding is correct, the reason should not be that the default grey is no longer available, because it is still used for all have always worked characters. The man page is correct and it _will_ only affect the last 256 glyphs. In fact these characters are always using a different colour. This is due to the old days when memory was expensive and engineers squeezed much into little. Simply said, as you can only encode 256 values into a byte, you are missing a bit for 512 character fonts. In order not to waste bytes, this bit is taken from the colour index nibble of the attribute byte. So the lower 256 characters use the colours with index 0-7 and the upper 256 characters the colours with index 8-15. The trick is to mirror the colours indexed by 0-7 to the ones indexed by 8-15. I would have to look whether this is done in the console driver. It is a bit hard to see for me as on my LCD this seems to be ntsc (nearly the same colour), so I never saw that difference. -- When all other means of communication fail, try words! -- Non-ASCII characters get corrupted in framebuffer console https://bugs.launchpad.net/bugs/355057 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 355057] Re: Non-ASCII characters get corrupted in framebuffer console
The man page is correct and it _will_ only affect the last 256 glyphs. You are right, I didn't read it carefully enough and understood it wrong. The trick is to mirror the colours indexed by 0-7 to the ones indexed by 8-15. If this were possible it would be another bug, because it does clearly not happen at least for my console. Or is there some limitation that the same color can only be used once and you have to use similar colors? Then people with poor monitors would have an advantage :) As said before I don't think this is high priority for me personally, because I prefer to use computers in English (as long as I can decide myself) and work in X11 (as long as I don't have to do trouble shooting). But if Ubuntu intends to be a localized system, it might of course be nice to eventually get the console working flawlessly also for languages using non-ASCII letters after so many years. -- Non-ASCII characters get corrupted in framebuffer console https://bugs.launchpad.net/bugs/355057 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 355057] Re: Non-ASCII characters get corrupted in framebuffer console
Hmm, your kernels are for Jaunty. I have only Hardy and Intrepid systems. I have reproduced the problem in Jaunty by using the live CD. But I guess I cannot update the kernel when using the live CD, can I? I can probably install a Jaunty to some disk corner, but I might take a couple of days or week until I find the time. Thanks for working on the patch! -- Non-ASCII characters get corrupted in framebuffer console https://bugs.launchpad.net/bugs/355057 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 355057] Re: Non-ASCII characters get corrupted in framebuffer console
Gosh, I think I found the little bugger. It seems this has been that way near forever but probably did not always matter (as long as your font only has 256 characters). The problem lies in the function that returns the font data of a vga console. It will only write back the first 256 characters but claims the returned font has 512 (as it had). So after every switch of the console there is the chance of corruption. Some of my systems seemed to have initially 256 character fonts, so your example text and also those special characters on my keyboard where fine. Just after loading a font with 512 characters in it you will immediately see the corruption. The attached patch fixed the problem for me. I will also upload some Jaunty based kernels with that fix, so you could test with them. Should this work for you as well, would it be ok to add you with your email as a Tested-by?

There are 2 more reports, which I originally thought they report the same issue. However, after reading them again, I decided not to mark them as duplicates, because they contain also other aspects, which might be unique to them.
