Frame buffer devices on unconventional monitor

To: debian-user@lists.debian.org Subject: Frame buffer devices on unconventional monitor From: Renato Carmo <renato@ime.usp.br> Date: Mon, 07 Aug 2000 21:12:50 -0300 Message-id: <20000808001250.28341.qmail@jaca.ime.usp.br> Hi there!

I use an adapted HP A2094-B monitor (an old 19'' monitor intended for HP workstations) which I adapted to use in a PC running Linux (the only way I can afford a 19'' monitor ... ;).

After getting the synch timings from HP and making the cabling, I got it to work fine with XFree86.

However the monitor has one single synchronization frequency (tech data goes at the end of this mail) and allows no use of text mode.

When I first heard about frame buffer devices, it sounded as the answer to my prayers ...

However, I tried to use fbset according to the instructions and got no satisfactory results.

I would be really grateful if anyone could shed some light on this ...

Tech info follows:


Video board: onboard SiS 530, 8Mb of the main memory as video memory. Motherboard: ASUS P5S-B rev 1.02, with a K6-500MHz and 128Mb of RAM.

Monitor technical data (from HP Service Notes pp. 8-3, 8-4) is:

   # Product Number: HP A2094B
   # Exchange Part Nymber: 2090-0315
   # Hemisphere: Southern
   # Size: 19'', 1280x1024 pixels
   # Refresh Rate: 72Hz
   # 
   # Cables: 98700-61603 BNC to BNC
   #         C2300-60005 9 pin to RGB
   #

   #         Horizontal display: 1280 pixels
   #         Vertical display: 1024 pixels
   # 
   # Horizontal:
   #         Horizontal frequency: 78.125 KHz
   #         Horizontal period: 12.800 microseconds (1H)
   #         Horizontal front porch: 0.474 microseconds (H-FP)
   #         Horizontal sync pulse width: 1.422 microseconds (H-SYNC)
   #         Horizontal back porch: 1.422 microseconds (H-BP)
   #         Horizontal blanking: 3.318 microseconds (H-BL)
   #         Horizontal display time: 9.482 microseconds (H-DISP)
   # 
   # Vertical:
   #         Fields per frame: 1
   #         Field fraquency: 72.005 Hz
   #         Field period: 13.888 ms (1 V) (1085 lines)
   #         Vertical front porch: 38.40 microseconds (V-FR) (3H)
   #         Vertical sync pulse width: 38.40 microseconds (V-SYNC) (3H)
   #         Vertical back porch: 704.0 microseconds (V-BP) (55H)
   #         Vertical blanking: 780.8 microseconds (V-BL) (61H)
   #         Vertical display time: 13.107 ms (V-DISP) (1024H)

Modeline (calculated manually) which works with XFree86:

   Modeline "1280x1024"   134.993    1280 1344 1536 1728    1024 1027 1030 1085

According to the instructions in Documentation/fb/framebuffer.txt, I calculated:

   Modeline "1280x1024"   134.993    1280 1344 1536 1728    1024 1027 1030 1085
                             DCF      HR   SH1  SH2  HFL     VR   SV1  SV2  VFL


  - pixclock: pixel clock in ps (pico seconds): 1000000 / DCF = 7407.79151512
  - left_margin: time from sync to picture:     HFL - SH2     = 192
  - right_margin: time from picture to sync:    SH1 - HR      = 64
  - upper_margin: time from sync to picture:    VFL - SV2     = 55
  - lower_margin: time from picture to sync:    SV1 - VR      = 3
  - hsync_len: length of horizontal sync:       SH2 - SH1     = 192
  - vsync_len: length of vertical sync:         SV2 - SV1     = 3

and so, started trying variations of

fbset -v -t 7407.40 192 64 55 3 192 3

To make it manageable, I made the following script


command="fbset -v -t 7407.40 192 64 55 3 192 3"

fbset -i -v -x > fbset.log echo ${command} >> fbset.log ${command} >> fbset.log 2>> fbset.log fbset -i -v -x >> fbset.log chmod 666 fbset.log


switched to vt1, blindly sourced it, switched back to X (vt5) and looked at the results in fbset.log;

Then I tried to figure out what else was needed, changed the string 'command' at the first line and started over again ...

The first try was promising: the call above gave me a screen out of synch but I could see big characters rolling up. Never have got so near ...

Although it seemed just a question of adjusting parameters, I couldn't go any farther.

At the end of this mail you can find the output of the script above for several runs.

I'll really appreciate any help you can give me.

Thanks in advance!
