I have such a problem, but only when running xfce4. TWM and IceWM are OK - gtk+2 dependency here? Tried to solve it with absolutely no success. All DGA 1/2 examples fail the same way as well, so it's not a vd_xfdga.c error. DGA is unstable, as noted... It'll be replaced in XFree86-5. Anyone else tested that? I can send you the DGA examples. -- E-gards: Jimmy

Testing the DGA driver

Hi Dimitar. I have retested your new DGA driver in 2.4.7p1 without the framebuffer: In my desktop with XFree86 4.2.0 I see a blak screen only. In my Toshiba with XFree86 4.3.0: ./xdemogrx and Hey! It seems to work, but returning to X the screen was cripped to a 640*480 window. I managed to run "./xdemogrx 1024 768 24" and it works, but funny things happen with the input, like if you have pressed the Return key all the time. Greetings, M.Alvarez

Hi Dimitar, Sorry for my ignorance, but I haven't heard about DGA, raw driver or psf2. Could you explain me something about all this? I use the drivers for Linux framebuffer and for Windows, and I would like to know if those changes affect me.

DGA driver v2 fix
by Dimitar Zhekov 12 Dec '03

12 Dec '03

Close the framebuffer if DGA is compiled with framebuffer support, not without it. Incremential, apply after xfdga-small-changes and dga-driver-v2. -- E-gards: Jimmy

RAW driver v2
by Dimitar Zhekov 12 Dec '03

12 Dec '03

Version 2 of the raw driver. Support for psf2. Better support for RAW: up to 16x32, assuming width:height 1:2 (the previous code was always assuming width = 8). -- E-gards: Jimmy

mingw-gpc compilation fails
by Gábor Peintler 28 Nov '03

28 Nov '03

Hi, I tried to compile GRX 2.4.6 with pascal support threough makefile.w32, however, the creation of the executables from pascal sources was not successful. The compiler always said that there an unknown reference to WinMain@16. I used gcc3.2.3+gpc3.2.3. Does somebody have any suggestion?

(PATCH) BUG in u_egavga.c - Incorrect behaviour when installed DISPLAY.SYS to display non-Latin characters
by Eugene Yavorsky 10 Nov '03

10 Nov '03

Hello, all! SYMPTOMS: When loaded driver DISPLAY.SYS to support fonts with characters from non-latin alphabets, such as Cyrillics, Hebrew, Central European, Baltic etc., after termination of GRX application, localized fonts not loaded and international characters displayed incorrectly until manual reset video mode. This happen always under TESTED SOFTWARE ENVIRONMENT: OPERATING SYSTEMS: MSDOS 7.0, 7.1; MS Windows 95, 98, SE, ME; MS Windows NT, 2000, (XP?) DISPLAY DRIVERS: DISPLAY.SYS from corresponding DOS/Windows installation (or 32-bit analog for NT family) KEYRUS - available to me alternative device driver. CAUSE: Before terminating GRX application, this library always calls setmode() to restore initial videomode, which first invoke corresponding VESA function, instead of INT 10H AH=0, as expected (and supported) by driver. SOLUTION: Forced call to INT 10H to reload ROM fonts (this function superceded by driver DISPLAY.SYS and loads localized fonts). See code below. (P.S. Excuse my terrible English. See my e-mail ;-) ======= begin "diff -c -p u_egavga.c.bak u_egavga.c" *** u_egavga.c.bak Sat Jan 20 03:11:28 2001 --- u_egavga.c Mon Nov 10 20:04:34 2003 *************** *** 22,27 **** --- 22,56 ---- #include "vesa.h" #include "memfill.h" + void _GrViDrvReLoadFonts(void) + { + GRX_ENTER(); + int86Regs r; + sttzero(&r); + + /* read font height to load appropriate ROM BIOS font */ + IREG_AX(r) = 0x1130; + IREG_BX(r) = 0x0000; + int10(&r); + + IREG_BL(r) = 0x0000; + + if(IREG_CX(r) == 16) + IREG_AX(r) = 0x1114; + else if(IREG_CX(r) == 14) + IREG_AX(r) = 0x1111; + else if(IREG_CX(r) == 8) + IREG_AX(r) = 0x1112; + else{ + DBGPRINTF(DBG_DRIVER, ("Strange font height = %d\n", IREG_CX(r))); + GRX_RETURN(); + } + + int10(&r); + + GRX_LEAVE(); + } + int _GrViDrvDetectEGAVGA(void) { Int86Regs r; *************** static int setmode(int mode,int noclear) *** 79,85 **** IREG_AX(r) = VESA_FUNC + VESA_SET_MODE; IREG_BX(r) = (mode & 0x7fff) | (noclear ? 0x8000U : 0); int10(&r); ! if(IREG_AX(r) == VESA_SUCCESS) return(TRUE); IREG_AX(r) = (mode & 0x7f) | (noclear ? 0x80U : 0); int10(&r); return((_GrViDrvGetCurrentEGAVGAmode() == mode) ?
