hrev53209 32bit Haiku

<BrunoSpr> I just test Haiku 32Bit nightly with my Pentium 4 computer and a Radeon HD 4710 (RV730) Grafic card...
[10:13:07] <BrunoSpr> nice 1920 x 1080 Screen resolution... works and looks great... but I cannot change the resolution!!! Will get a blank screen if I try to...
[10:13:41] <BrunoSpr> Is this problem known? Where to check if this is reported or not?
[10:16:07] <diver> BrunoSpr: what graphics card do you have?
[10:16:12] <diver> ah
[10:16:44] <BrunoSpr> It is a radeon Hd 4710 (Rv730)
[10:16:54] <diver> here https://dev.haiku-os.org/query?status=assigned&status=in-progress&status=new&status=reopened&component=Drivers%2FGraphics%2Fradeon_hd&order=priority
[10:16:57] <BrunoSpr> works great so far...
[10:17:22] <BrunoSpr> ah ok thx Diver
[10:17:41] <BrunoSpr> Just found this info: https://dev.haiku-os.org/wiki/HardwareInfo/video/RadeonHD_tech
[10:17:59] <diver> looks like this problem is not reported yet
[10:18:42] <diver> go ahead and file a ticket
[10:20:06] <diver> also, open Terminal and run tail -F /var/log/syslog and try to change the resolution again (and revert) and see if it outputs anything useful
[10:20:13] <BrunoSpr> I use it with an DVI adapter and HDMI ... is this a problem?
[10:20:24] <BrunoSpr> worth reporting?
[10:20:27] <diver> could be, yeah
[10:20:29] <diver> sure
[10:23:11] <BrunoSpr> ah ya sure... some programs and more games will change the resolution to say 800x 600 and then you will get a black screen and not way back exept changing the workspace... is it?
[10:23:36] <BrunoSpr> 95dpi is normal?
[10:24:02] <BrunoSpr> 1920 x 1080 32bit 60Hz... and 95dpi?
[10:25:11] <BrunoSpr> ok thx for now have to work soon... will file a bug later then... with syslog ? and listdev? what else is useful for fast way...?
[10:26:38] <diver> BrunoSpr: SDL games do that, yeah
[10:27:04] <diver> eyp, syslog and listdev should do
[10:28:51] <yep> k thx yes SDL games are a problem to use... also in screen preferences it should be this workspace only for standard not all workspaces... so the user will not lead to black screen...
[10:29:36] <BrunoSpr> so it will affect only the actual workspace/screen is it?
[10:37:55] <diver> BrunoSpr: it's a bug in our SDL port

Radeon HD 4710 (RV730) works with 1920 x 1080 32 Bit 60Hz Haiku 32Bit only!

I can use this one resolution only... changing the resolution will result in black blank screen.. I have not found another working resolution... After switching to another screen size, there is not way back!

I have to delete: ~/config/settings/system/app_server/workspaces from another Haiku install... to make Haiku boot in 1920 x1080.. I blacklisted the firewire driver to make Haiku work...
