Daplas" Subject: vgacon regression Cc: Andrew Morton , Linus Torvalds , Linux Kernel Mailing List MIME-Version: 1.0 Content-Type: text/plain; charset=US-ASCII Content-Transfer-Encoding: 7BIT Content-Disposition: inline Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Hi Antonino, [starting a new thread and adding Linus to CC since this problem is now also in his tree as well as Andrews] The problem I observed in 2.6.15-rc5-mm2 with the (vgacon) console getting corrupted after starting X is still present in 2.6.15-rc5-mm3 and is now also present in mainline (2.6.15-rc6-git1). Latest kernel that I know of that is problem free is 2.6.15-rc5-git4. The problem in a nutshell: If I boot with vga=791 everything is fine with both mainline kernels and -mm and I don't see any of the problems noted below. If I boot with vga=normal then I see these two problems : 1) Just after starts and switches resolution but before the login manager is displayed I briefly see a corrupted graphical image that is sometimes what looks like a garbled snapshot of the text-mode console and sometimes a garbled version of the X login screen or a previous KDE desktop session. 2) If I switch back to a text mode console with ctrl+alt+f6 from within X (or even shut down X), then the text console is completely garbled. It still has the resolution it had at boot but it's displaying lots of coloured (some of them blinking) boxes and random characters all over, including some bits that look like partial boot-up messages (half a word here, two words there, with random bits inserted, etc) - in short, it's completely messed up. The console stil remains functional in the sense that you can log in blind and run commands just fine, but no amount of "reset" or "clear" will fix the breakage. Any advice as to what patches I can try to revert? While I wait for a reply I'll test the mainline kernels between 2.6.15-rc5-git4 and 2.6.15-rc6-git1 to try and determine the first one that breaks. -- Jesper Juhl Don't top-post http://www.catb.org/~esr/jargon/html/T/top-post.html Plain text mails only, please http://www.expita.com/nomime.html
