I just finished trouble shooting a "Sync out of range" message on my Viewsonic VG800 LCD panels, which take an analog input. In my case, i recieved the message when leaving X, or when I toggled from X to a virtual (text) console. My problem was in an incorrect setting in my lilo.conf file, despite the fact that upon booting, my console functioned fine. This could be your problem too. for example, X may try to start, but fail, then X sends you back to an incorrect console mode. Note that two generous subscribers tried valiantly to help me. But every one was focusing on X, when X was not the problem. In the end it was by chance that i figured out the solution. Below are the details. The row (color resolution) was not important in my case. Instead, it was the column that was important. It might be helpful for you to know that before i finally figured out problem, I tried many different HorizSync and VertRefresh values/ranges - even ranges that went beyond my panel's capabilities - and that X performed fine with all of them (as long as i didn't have a typo in XFConfig. Note that X may not be starting for you for this very reason). Also, i do not have any modelines in my XFConfig file - i remember reading somewhere that these days, X generates the appropriate mode line by probing the hardware. Here is another twist to the story: it turns out that my settings in the XFConfig file were affecting my console mode! even when X was not running! A minor problem that i was having in console mode was that all the text lines were shifted about four characters off the screen. X was running perfectly, but whenever I left X, the console was shifted! Details on how i fixed this are at the bottom. Apart from these two issues, X has always worked fine "out of the box" for me, so i am not an expert in any sense. >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> > > i fixed this problem, as root, by editing /etc/lilo.conf, then running the command lilo. > > in particular, i changed > vga=791 > to > vga=795 (or any other value in that column) > then ran lilo. > > appearantly, 791 was fine for my 1024x768 panels > but a different value is need for 1280x1024 panels > > here is a table that i ripped off from > http://www.uno.edu/~adamico/banshee/files/vesafb.txt > > Colours 640x480 800x600 1024x768 1280x1024 1600x1200 > --------+--------------------------------------------- > 256 | 769 771 773 775 796 > 32,768 | 784 787 790 793 797 > 65,536 | 785 788 791 794 798 > 16.8M | 786 789 792 795 799 > > > there remains a problem. it is the same problem that i > > had with my 1024x768 panels. whenever i leave X, the > > first 4 columns of texmode are shifted off the screen > > (the whole screen is shifted to the left by four columns) > > this is not the case upon a cold boot, but only with textmode > > of VCs or leaving X. >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> > > > i posted this problem yesterday at the end of a different > thread on the newbie list. > > i fixed the problem by changing the line: > > VertRefresh 50-75 > > to > > VertRefresh 60 > > in my /etc/X11/XF86Config-4 file. > > Under X, the VG800 panels' On Screen Display (OSD) now report > Resolution: 1280x1024 > Frequency: H: 64.0 KHz > V: 60.0 Hz > > and the virtual consoles are no longer shifted 4 columns off screen, > nor is textmode upon leaving X. ==================================================================== ==================================================================== __________________________________________________ Do you Yahoo!?
