After upgrade of xorg-server from 1.16 to 1.17 I get the following error: [ 1327.041] (II) R128(0): initializing int10 [ 1327.041] (EE) R128(0): Cannot read int vect [ 1327.041] (--) R128(0): Chipset: "ATI Rage 128 Pro ULTRA TF (AGP)" (ChipID = 0x5446) [ 1327.041] (--) R128(0): Linear framebuffer at 0xf8000000 [ 1327.041] (--) R128(0): MMIO registers at 0xfe9fc000 [ 1327.041] (EE) [ 1327.043] (EE) Backtrace: [ 1327.044] (EE) 0: /usr/lib/xorg-server/Xorg (xorg_backtrace+0x52) [0x81db3f2] [ 1327.045] (EE) 1: /usr/lib/xorg-server/Xorg (0x8048000+0x197612) [0x81df612] [ 1327.047] (EE) 2: linux-gate.so.1 (__kernel_rt_sigreturn+0x0) [0xb7768b94] [ 1327.047] (EE) 3: /usr/lib/xorg/modules/drivers/r128_drv.so (0xb6e30000+0x60b3) [0xb6e360b3] [ 1327.047] (EE) 4: /usr/lib/xorg-server/Xorg (InitOutput+0xa23) [0x80bf363] [ 1327.047] (EE) 5: /usr/lib/xorg-server/Xorg (0x8048000+0x369da) [0x807e9da] [ 1327.047] (EE) 6: /usr/lib/xorg-server/Xorg (0x8048000+0x20a1a) [0x8068a1a] [ 1327.047] (EE) 7: /usr/lib/libc.so.6 (__libc_start_main+0xde) [0xb72f264e] [ 1327.047] (EE) 8: /usr/lib/xorg-server/Xorg (0x8048000+0x20a48) [0x8068a48] [ 1327.047] (EE) [ 1327.047] (EE) Segmentation fault at address 0x15 [ 1327.047] (EE) Fatal server error: [ 1327.047] (EE) Caught signal 11 (Segmentation fault). Server aborting [ 1327.047] (EE) [ 1327.047] (EE) I can get rid of the "Cannot read int vect" with Option NoInt10 "True" but: - I still get the segfault with xorg-server 1.17 - when doing this with the xorg-server 1.16 (on which I didn't have this message) I cannot get high resolutions (1920x1080), only 1024x768 at best Don't hesitate to tell me if I can do something to provide more information.

Thanks for reporting this. I have noticed two regressions for this driver between xorg-server 1.16 and 1.17. 1. Important headers refusing to be found at compile time. 2. Int10 breaking. If this crash (which has affected at least one other person) is due to #1, then I've already fixed it. So you can try to compile the latest git. However, I suspect the crash is due to #2. If that's the case, I'll have to bisect for awhile to eventually get to the bottom of this. Also, I'm not surprised that disabling Int10 prevents certain resolutions from working. Int10 brings up the VBIOS and that's where adjustments to certain video modes are stored.
Update. #2 has recently been fixed on the development list. It requires an xorg-server patch: http://patchwork.freedesktop.org/patch/41957/ If you can test this, it would be great.
I'm quite sure this is fixed in xf86-video-r128 commit cd72de385b5600229226c3a7248a89569b452136. Please reopen this bug if it's not.
Created attachment 115983 [details] Xorg.0.log from openSUSE Tumbleweed, kernel 4.0.3, server 1.17.1 and r128 driver 6.10.0 Maybe this isn't fixed? 01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Rage 128 PRO Ultra AGP 4x Same machine seems OK with openSUSE 13.2, kernel 3.16.7, server 1.16.1 and r128 driver 6.9.2.
The segfault has been fixed. What you're seeing is the upstream int10 bug that happened between servers 1.16 and 1.17. Are you able to build the patched server? http://cgit.freedesktop.org/xorg/xserver/commit/?id=0a78b599b34cc8b5fe6fe82f90e90234e8ab7a56 If not, you can try asking the people on xorg-devel to backport it. That way maybe it will come out before 1.18.
